Estudo endócrino reprodutivo e do comportamento sócio-sexual de sagui-de-tufo-preto (Callithrix penicillata) mantido em cativeiro

A comunicação do estado reprodutivo nos primatas da família Callithrichidae, depende principalmente dos comportamentos sócio-sexuais como um sistema de sinalização primário, uma vez que nestas espécies a ovulação não é percebida pelos machos. Neste trabalho, os padrões de comportamentos sócio-sexuais foram analisados em conjunto com as concentrações de metabólitos fecais dos esteróides sexuais progesterona (MFP), estradiol (MFE) e testosterona (MFT) em casais cativos de Sagüi-de-tufos-pretos (Callithrix penicillata), nas diferentes fases do ciclo ovariano. O grupo estudado era composto por quarto casais adultos, mantidos no Centro de Reabilitação de Animais Selvagens da prefeitura de São Paulo. Os padrões comportamentais foram registrados pelo método de amostragem focal por intervalo de tempo a cada 30 segundos, cinco vezes por semana, totalizando 14.400 registros por animal. A mensuração das concentrações de metabólitos fecais dos esteroides sexuais foram realizados pelo método de enzima imunoensaio (EIE). Os resultados obtidos dessas concentrações possibilitaram a determinação endócrina das fases do ciclo ovariano (folicular e luteal) e de suas respectivas durações, assim como a determinação da fase periovulatória. Foram caracterizados 31 ciclos ovarianos completos, com duração de 24,3±4,1 dias (média ±DP), sendo que a fase folicular compreendeu 13,04±4,8dias e a fase lútea 11,2±4,2 dias. Os comportamentos sócio-sexuais (marcação por cheiro, cheirar genitália, catação e apresentação sexual) e a variável "proximidade" mostraram-se significativamente mais prevalentes na fase periovulatória do que nas demais fases do ciclo. Não houve alteração das concentrações de MFT dos machos ao longo de todo o período estudado. A análise conjunta das concentrações de metabólitos fecais de esteróides sexuais e dos comportamentos sócio-sexuais possibilitou um melhor entendimento das relações endócrino-comportamentais e reprodutivas de C. penicillata

Delayed mucosal antiviral responses despite robust peripheral inflammation in fatal COVID-19

Background While inflammatory and immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in peripheral blood are extensively described, responses at the upper respiratory mucosal site of initial infection are relatively poorly defined. We sought to identify mucosal cytokine/chemokine signatures that distinguished coronavirus disease 2019 (COVID-19) severity categories, and relate these to disease progression and peripheral inflammation. Methods We measured 35 cytokines and chemokines in nasal samples from 274 patients hospitalized with COVID-19. Analysis considered the timing of sampling during disease, as either the early (0–5 days after symptom onset) or late (6–20 days after symptom onset) phase. Results Patients that survived severe COVID-19 showed interferon (IFN)-dominated mucosal immune responses (IFN-γ, CXCL10, and CXCL13) early in infection. These early mucosal responses were absent in patients who would progress to fatal disease despite equivalent SARS-CoV-2 viral load. Mucosal inflammation in later disease was dominated by interleukin 2 (IL-2), IL-10, IFN-γ, and IL-12p70, which scaled with severity but did not differentiate patients who would survive or succumb to disease. Cytokines and chemokines in the mucosa showed distinctions from responses evident in the peripheral blood, particularly during fatal disease. Conclusions Defective early mucosal antiviral responses anticipate fatal COVID-19 but are not associated with viral load. Early mucosal immune responses may define the trajectory of severe COVID-19

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely

SARS-CoV-2-specific nasal IgA wanes 9 months after hospitalisation with COVID-19 and is not induced by subsequent vaccination

BACKGROUND: Most studies of immunity to SARS-CoV-2 focus on circulating antibody, giving limited insights into mucosal defences that prevent viral replication and onward transmission. We studied nasal and plasma antibody responses one year after hospitalisation for COVID-19, including a period when SARS-CoV-2 vaccination was introduced. METHODS: In this follow up study, plasma and nasosorption samples were prospectively collected from 446 adults hospitalised for COVID-19 between February 2020 and March 2021 via the ISARIC4C and PHOSP-COVID consortia. IgA and IgG responses to NP and S of ancestral SARS-CoV-2, Delta and Omicron (BA.1) variants were measured by electrochemiluminescence and compared with plasma neutralisation data. FINDINGS: Strong and consistent nasal anti-NP and anti-S IgA responses were demonstrated, which remained elevated for nine months (p < 0.0001). Nasal and plasma anti-S IgG remained elevated for at least 12 months (p < 0.0001) with plasma neutralising titres that were raised against all variants compared to controls (p < 0.0001). Of 323 with complete data, 307 were vaccinated between 6 and 12 months; coinciding with rises in nasal and plasma IgA and IgG anti-S titres for all SARS-CoV-2 variants, although the change in nasal IgA was minimal (1.46-fold change after 10 months, p = 0.011) and the median remained below the positive threshold determined by pre-pandemic controls. Samples 12 months after admission showed no association between nasal IgA and plasma IgG anti-S responses (R = 0.05, p = 0.18), indicating that nasal IgA responses are distinct from those in plasma and minimally boosted by vaccination. INTERPRETATION: The decline in nasal IgA responses 9 months after infection and minimal impact of subsequent vaccination may explain the lack of long-lasting nasal defence against reinfection and the limited effects of vaccination on transmission. These findings highlight the need to develop vaccines that enhance nasal immunity. FUNDING: This study has been supported by ISARIC4C and PHOSP-COVID consortia.

Large-scale phenotyping of patients with long COVID post-hospitalization reveals mechanistic subtypes of disease

One in ten severe acute respiratory syndrome coronavirus 2 infections result in prolonged symptoms termed long coronavirus disease (COVID), yet disease phenotypes and mechanisms are poorly understood1. Here we profiled 368 plasma proteins in 657 participants ≥3 months following hospitalization. Of these, 426 had at least one long COVID symptom and 233 had fully recovered. Elevated markers of myeloid inflammation and complement activation were associated with long COVID. IL-1R2, MATN2 and COLEC12 were associated with cardiorespiratory symptoms, fatigue and anxiety/depression; MATN2, CSF3 and C1QA were elevated in gastrointestinal symptoms and C1QA was elevated in cognitive impairment. Additional markers of alterations in nerve tissue repair (SPON-1 and NFASC) were elevated in those with cognitive impairment and SCG3, suggestive of brain–gut axis disturbance, was elevated in gastrointestinal symptoms. Severe acute respiratory syndrome coronavirus 2-specific immunoglobulin G (IgG) was persistently elevated in some individuals with long COVID, but virus was not detected in sputum. Analysis of inflammatory markers in nasal fluids showed no association with symptoms. Our study aimed to understand inflammatory processes that underlie long COVID and was not designed for biomarker discovery. Our findings suggest that specific inflammatory pathways related to tissue damage are implicated in subtypes of long COVID, which might be targeted in future therapeutic trials

Significant reduction of fungal disease symptoms in transgenic lupin (Lupinus angustifolius) expressing the anti-apoptotic baculovirus genep35

Narrow-leafed lupin (NLL; Lupinus angustifolius) is a recently domesticated but anciently propagated crop with significant value in rotation with cereals in Mediterranean climates. However, several fungal pathogens, traditionally termed necrotrophs, severely affect broad-acre production and there is limited genetic resistance in the NLL germplasm pool. Symptoms of many of these diseases appear as localized areas of dead cells exhibiting markers of programmed cell death. Based on our previous research, we hypothesized that engineered expression of the baculovirus anti-apoptotic p35 gene might reduce symptoms of these diseases. Using Agrobacterium tumefaciens-mediated transformation of a cultivar highly susceptible to several pathogens, 14 independent NLL lines containing both the p35 and bar genes were obtained (p35-NLL). Integration and expression of the transgenes were confirmed by polymerase chain reaction (PCR), progeny testing, Southern blot, Northern blot and reverse transcriptase-PCR analyses. Fecundity and nodulation were not altered in these lines. Third or fourth generation p35-NLL lines were challenged with necrotrophic fungal pathogens (anthracnose in stem and leaf, and Pleiochaeta root rot and leaf brown spot) in controlled environment conditions. Several p35-NLL lines had significantly reduced disease symptoms. Interestingly, as with natural resistance, no single line was improved for all three diseases which possibly reflecting spatial variation of p35 expression in planta. These data support an alternative molecular definition for 'necrotrophic disease' in plants and suggest new routes for achieving resistance against a range of pathogens

Programmed cell death suppression in transformed plant tissue by tomato cDNAs identified from an Agrobacterium rhizogenes-based functional screen

The genetic regulation of programmed cell death (PCD) is well characterized in animal systems, but largely unresolved in plants. This research was designed to identify plant genes that can suppress PCD triggered in plants by Fumonisin B1 (FB1). Agrobacterium rhizogenes was used to transform individual members of a cDNA library into tomato roots, which were then screened for resistance to FB1. Cellular changes elicited during FB1-induced PCD include chromatin condensation, fragmentation into pycnotic DNA bodies, TUNEL positive reactions, ROS accumulation, and eventual loss of membrane integrity. Several cDNA library members collectively overexpressed in a transformed root population revealed PCD suppressive action and were recovered by PCR. One of the FB1 suppressive genes was homologous to metallothionein, and shared sequence homology to the animal ortholog reported to suppress PCD through interference with formation or activity of reactive oxygen species (ROS). The metallothionein recovered in this screen suppressed ROS accumulation in FB1-treated roots and prevented symptoms of PCD. Anti-PCD genes recovered by this screen represent potential sources of resistance to PCD-dependent plant diseases, while the screen should be useful to identify genes capable of suppressing PCD triggered by other effectors, including those expressed by root pathogens during infection

236 effect of cyclic adenosine monophosphate modulator regulators in association with bmp15 on bovine embryo development in vitro

Proceedings of the Annual Conference of the International Embryo Transfer Society, Versailles, France, 10–13 January 2015BMP15 is a promising peptide to improve oocyte competence; also, addition of cyclic adenosine monophosphate modulator (cAMP) regulators prevents spontaneous maturation in vitro and promotes embryo development. We aimed to assess embryo development after prematuration [pre-in vitro maturation (IVM)] with IBMX and Forskolin (FSK) and maturation in the presence or absence of a purified pro mature region of BMP15. Immature cumulus-oocyte complexes (COC) were cultured in vitroMat (IVF Vet Solutions, Adelaide, Australia) plus 4mgmL(-1) fatty acid free-BSA and rhFSH (0.1IUmL(-1)), then divided into the following treatment groups: 1) spontaneous IVM: 24h of IVM; 2) spontaneous IVM+BMP15: 24h of IVM in the presence of BMP15 (100ngmL(-1)); 3) Pre 2 h: pretreatment with IBMX (500µM; Sigma-Aldrich) and FSK (100µM; Sigma-Aldrich) for 2h following 24h maturation; and 4) Pre 2 h+BMP15: pretreatment with IBMX and FSK for 2h following 24h maturation in the presence of BMP15 (100ngmL(-1)). After maturation, oocytes were inseminated and zygotes were cultured for 5 days in VitroCleave (IVF Vet Solutions, Adelaide, Australia) and transferred into VitroBlast (IVF Vet Solutions, Adelaide, Australia) until blastocyst assessment (Days 7 and 8). Zona-intact embryos were retrieved to assess differential staining of trophectoderm and inner cell mass. Data were transformed into a logarithm and analysed by 1-way ANOVA and post hoc least significant difference using SigmaStat software (SPSS Inc., San Jose, CA, USA; P<0.05). There was no difference among groups on cleavage rates or blastocyst rates at Day 7; however, both Pre 2h treatments increase hatched blastocyst rates at Day 8 of embryo development (Table 1). Supplementation with BMP15 increased total blastocyst rates at Day 8, regardless of pretreatment with IBMX+FSK (Table 1). Our data demonstrate that embryos from oocytes matured in the presence of BMP15 or pretreated with IBMX+FSK increase trophectoderm and total cell numbers; however, no differences were observed for inner cell mass. We conclude that Pre 2h treatment or BMP15 increase embryo development; however, no effect of cAMP regulators in association with BMP15 on embryo development was observed.M. F. Machado, M. F. G.
