The cross-regulation between h1 and h2 histamine receptors modulates the behavior of h2 receptor blockers
Histamine modulates severalbiological processes, including allergy and gastric acid secretion, through H1and H2 receptors (H1R, H2R). H2R blockers are mainlyused to treat gastrointestinaldisorders, such as gastric acid secretion and there is much interest on theirrepositioning for other pathologies. Thus, deepunderstanding of theirmechanisms of action is needed. We have previously described that H1R and H2Ragonists induce the receptor?s co-internalization andcross-desensitization. We havealso reported that H2R blockers lead to desensitization and internalization ofH2 receptor.The aim of this work was tostudy the capacity of H2R blockers (cimetidine, ranitidine and famotidine) toinduce the H1R cross-desensitization and how thismechanism affects the behaviorof H2R blockers. In this way, we used promonocytic U937 cells (endogenouslyexpressing H1R and H2R), PMA-differentiated U937cells and HEK293 cellstransiently transfected with one or both receptors.Fil: Díaz Nebreda, Antonela.

Effects of Occupational Therapy Program Based on Active Meditation on Hair Cortisol Levels in Undergraduate Healthcare Students
Context. Meditation incorporation helps to fight against disorders such as depression, stress, and anxiety. Specifically, few studies have studied Osho's Active Meditation on young people, but observed evidence using passive meditation shows that it could improve stress well-management, emotional control, and other mental unhealthy conditions. Goal. The present study pointed to evaluate the results of an occupational therapy program centered on active meditation on hair cortisol concentration in a sample of undergraduate healthcare students. Methods. Undergraduate students from the University of Chile's health careers were divided at random into control (n=7) and treated groups (n=15). The treated group participated in an active meditation program once a week for three months. This treatment included different techniques such as Chakra Sounds, Nataraj, Mandala, Kundalini, Devavani, Gourishankar, and Nadabrahma. Hair samples were taken before and after the treatment period to measure cortisol. Results. The control group increased cortisol level 168.9±76.8 pg/mg compared with initial levels. The treated group shows a decrease of initial cortisol values in 28.5±12.8 pg/mg after meditation protocol application. Conclusions. Blending active meditation in students' daily routine through occupational therapy intervention might prevent undergraduate students' stress in healthcare careers.Fil: Espinosa, Alejandra.

MRP4/ABCC4 expression is regulated by histamine in acute myeloid leukemia cells, determining cAMP efflux
Intracellular cAMP (i-cAMP) levels play an important role in acute myeloid leukemia (AML) cell proliferation and differentiation. Its levels are the result of cAMP production, degradation, and exclusion. We have previously described histamine H2 receptors and MRP4/ABCC4 as two potential targets for AML therapy. Acting through histamine H2 receptors, histamine increases cAMP production/synthesis, while MRP4/ABCC4 is responsible for the exclusion of this cyclic nucleotide. In this study, we show that histamine treatment induces MRP4/ABCC4 expression, augmenting cAMP efflux, and that histamine, in combination with MRP inhibitors, is able to reduce AML cell proliferation. Histamine, through histamine H2 receptor, increases i-cAMP levels and induces MRP4 transcript and protein levels in U937, KG1a, and HL-60 cells. Moreover, histamine induces MRP4 promoter activity in HEK293T cells transfected with histamine H2 receptor (HEK293T-H2R). Our results support that the cAMP/Epac-PKA pathway, and not MEK/ERK nor PI3K/AKT signaling cascades, is involved in histamine-mediated upregulation of MRP4 levels. Finally, the addition of histamine potentiates the inhibition of U937, KG1a, and HL-60 cell proliferation induced by MRP4 inhibitors. Our data highlight that the use of a poly-pharmacological approach aimed at different molecular targets would be beneficial in AML treatment.Fil: Rodriguez Gonzalez, Angela Paola.

Involvement of histamine H1 and H2 receptor inverse agonists in receptor's crossregulation
Histamine [2-(4-Imidazolyl)-ethylamine] modulates different biological processes, through histamine H1 and H2 receptors, and their respective blockers are widely used in treating allergic and gastric acid-related disorders. Histamine H1 and H2 receptor crossdesensitization and cointernalization induced by its agonists have been previously described. In this study, we show how this crosstalk determines the response to histamine H1 and H2 receptor inverse agonists and how histamine H1 and H2 receptor inverse agonists interfere with the other receptor's response to agonists. By desensitization assays we demonstrate that histamine H1 and H2 receptor inverse agonists induce a crossregulation between both receptors. In this sense, the histamine H1 receptor inverse agonists desensitize the cAMP response to amthamine, a histamine H2 receptor agonist. In turn, histamine H2 receptor inverse agonists interfere with histamine H1 receptor signaling. We also determine that the crossdesensitization induced by histamine H1 or H2 receptor agonists alters the histamine inverse agonists receptor response: activation of histamine H1 receptor affects cAMP response induced by histamine H2 receptor inverse agonists, whereas histamine H2 receptor agonist induces a negative regulation on the anti-inflammatory response of histamine H1 receptor inverse agonists. Binding studies revealed that histamine H1 and H2 receptors cointernalize after stimulus with histamine receptor inverse agonists. In addition, the inhibition of the internalization process prevents receptor crossregulation. Our study provides new insights in the mechanisms of action of histamine H1 and H2 receptors that explain the effect of histamine H1 and H2 receptor inverse agonists and opens up new venues for novel therapeutic applications.Fil: Díaz, Antonela Susana.

Cardiovascular morbidity and associated risk factors in Spanish patients with chronic inflammatory rheumatic diseases attendingrheumatology clinics: Baseline data of the CARMA Project
Objective: To establish the cardiovascular (CV) morbidity and associated risk factors for CV disease (CVD) in Spanish patients with chronic inflammatory rheumatic diseases (CIRD) and unexposed individuals attending rheumatology clinics. Methods: Analysis of data from the baseline visit of a 10-year prospective study [CARdiovascular in rheuMAtology (CARMA) project] that includes a cohort of patients with CIRD [rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)] and another cohort of matched individuals without CIRD attending outpatient rheumatology clinics from 67 hospitals in Spain. Prevalence of CV morbidity, CV risk factors, and systematic coronary risk evaluation (SCORE) assessment were analyzed. Results: A total of 2234 patients (775 RA, 738 AS, and 721 PsA) and 677 unexposed subjects were included. Patients had low disease activity at the time of recruitment. PsA patients had more commonly classic CV risk factors and metabolic syndrome features than did the remaining individuals. The prevalence of CVD was higher in RA (10.5%) than in AS (7.6%), PsA (7.2%), and unexposed individuals (6.4%). A multivariate analysis adjusted for the presence of classic CV risk factors and disease duration revealed a positive trend for CVD in RA (OR = 1.58; 95% CI: 0.90-2.76; p = 0.10) and AS (OR = 1.77; 95% CI: 0.96-3.27; p = 0.07). Disease duration in all CIRD groups and functional capacity (HAQ) in RA were associated with an increased risk of CVD (OR = 2.15; 95% CI: 1.29-3.56; p = 0.003). Most patients had a moderate CV risk according to the SCORE charts. Conclusions: Despite recent advances in the management of CIRD, incidence of CVD remains increased in Spanish subjects with CIRD attending outpatient rheumatology clinics

The Development of the Bengamides as New Antibiotics against Drug-Resistant Bacteria
The bengamides comprise an interesting family of natural products isolated from sponges belonging to the prolific Jaspidae family. Their outstanding antitumor properties, coupled with their unique mechanism of action and unprecedented molecular structures, have prompted an intense research activity directed towards their total syntheses, analogue design, and biological evaluations for their development as new anticancer agents. Together with these biological studies in cancer research, in recent years, the bengamides have been identified as potential antibiotics by their impressive biological activities against various drug-resistant bacteria such as Mycobacterium tuberculosis and Staphylococcus aureus. This review reports on the new advances in the chemistry and biology of the bengamides during the last years, paying special attention to their development as promising new antibiotics. Thus, the evolution of the bengamides from their initial exploration as antitumor agents up to their current status as antibiotics is described in detail, highlighting the manifold value of these marine natural products as valid hits in medicinal chemistry.Supported by grants RTI2018-098296-BI00 (Ministerio de Ciencia e Innovación), PI19/01478 from Instituto de Salud Carlos III (ISCIII) (FEDER), P20_00540 (Andalusian Government and FEDER), K99GM138758 and R35GM136286 (National Institute of General Medical Sciences of the National Institutes of Health), A-CTS-666-UGR20 (University of Granada) (FEDER), CTS-107 (Andalusian Government) and 2021-GRIN-30998 (University of Castilla-La Mancha).

Dopaminergic control of ADAMTS2 expression through cAMP/CREB and ERK: molecular effects of antipsychotics
A better understanding of the molecular mechanisms that participate in the development and clinical manifestations of schizophrenia can lead to improve our ability to diagnose and treat this disease. Previous data strongly associated the levels of deregulated ADAMTS2 expression in peripheral blood mononuclear cells (PBMCs) from patients at first episode of psychosis (up) as well as in clinical responders to treatment with antipsychotic drugs (down). In this current work, we performed an independent validation of such data and studied the mechanisms implicated in the control of ADAMTS2 gene expression. Using a new cohort of drug-naïve schizophrenia patients with clinical follow-up, we confirmed that the expression of ADAMTS2 was highly upregulated in PBMCs at the onset (drug-naïve patients) and downregulated, in clinical responders, after treatment with antipsychotics. Mechanistically, ADAMTS2 expression was activated by dopaminergic signalling (D1-class receptors) and downstream by cAMP/CREB and mitogen-activated protein kinase (MAPK)/ERK signalling. Incubation with antipsychotic drugs and selective PKA and MEK inhibitors abrogated D1-mediated activation of ADAMTS2 in neuronal-like cells. Thus, D1 receptors signalling towards CREB activation might participate in the onset and clinical responses to therapy in schizophrenia patients, by controlling ADAMTS2 expression and activity. The unbiased investigation of molecular mechanisms triggered by antipsychotic drugs may provide a new landscape of novel targets potentially associated with clinical efficacy.Acknowledgements: We are highly indebted to the participants and their families for their cooperation in this study.

Risk factors for graft loss and mortality after renal transplantation according to recipient age: a prospective multicentre study
Producción CientíficaBackground. To describe the causes of graft loss, patient death and survival figures in kidney transplant patients in Spain based on the recipient’s age. Methods. The results at 5 years of post-transplant cardiovascular disease (CVD) patients, taken from a database on CVD, were prospectively analysed, i.e. a total of 2600 transplanted patients during 2000–2002 in 14 Spanish renal transplant units, most of them receiving their organ from cadaver donors. Patients were grouped according to the recipient’s age: Group A: 60 years. The most frequent immunosuppressive regimen included tacrolimus, mycophenolate mofetil and steroids. Results. Patients were distributed as follows: 25.85% in Group A (>40 years), 50.9% in Group B (40–60 years) and 23.19% in Group C (>60). The 5-year survival for the different age groups was 97.4, 90.8 and 77.7%, respectively. Death-censored graft survival was 88, 84.2 and 79.1%, respectively, and non death-censored graft survival was 82.1, 80.3 and 64.7%, respectively. Across all age groups, CVD and infections were the most frequent cause of death. The main causes of graft loss were chronic allograft
dysfunction in patients 1 g at 6 months post-transplantation were statistically significant in the three age groups. The patient survival multivariate analysis did not achieve a statistically significant common factor in the three age groups.
Conclusions. Five-year results show an excellent recipient survival and graft survival, especially in the youngest age group. Death with functioning graft is the leading cause of graft loss in patients >40 years. Early improvement of renal function and proteinuria together with strict control of cardiovascular
risk factors are mandatory
Renal transplantation in the modern immunosuppressive era in Spain: four-year results from a multicenter database focus on post-transplant cardiovascular disease
Producción CientíficaTo evaluate cardiovascular disease (CVD) after renal transplantation we established a CVD database
(no-intervention) including all patients transplanted among 2000–2002 in 14 hospitals from Spain (Renal Forum Group) (n¼2600). They were prospective followed annually thereafter and we present herein the most important results concerning survival figures and CVD at four years. Mean recipient age was 49.7±13.7 years: 16% retransplanted and 12.5% hyperimmunized. Tacrolimus, mycophenolate
mofetil, and steroids was used in 63%. Acute rejection (AR) rate at 1 year was 14.8%. Graft and patient survival at 48 months were 85.6% (death censored) and 91.7% respectively. The first cause of graft loss was vascular in the first year, death with function during the 2–3 years, and chronic allograft nephropathy at the 4th year. Donor age, time on dialysis, acute tubular necrosis (ATN), AR, SCr at 6
months, the use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in the first year, and systolic blood pressure at 24 months were independent risk factors for graft loss at 4th year. The first cause of death was CVD (predominantly ischemic heart disease (IHD) in the first year). Recipient age, ATN, and SCr at 6 months were independent predictors of mortality. Despite
worsening of donor age, comorbidity, and advanced age of recipients, survival figures at four years are considered good in our Spanish non-selected population. Cardiovascular mortality is the most important cause of death and graft loss particularly, IHD in the first year. Therefore, to decrease post-transplant mortality a careful cardiovascular evaluation and treatment in the waiting list and a close follow-up of patients after transplantation is mandatory
