COVID-19 Is a multi-organ aggressor : epigenetic and clinical marks

The progression of coronavirus disease 2019 (COVID-19), resulting from a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, may be influenced by both genetic and environmental factors. Several viruses hijack the host genome machinery for their own advantage and survival, and similar phenomena might occur upon SARS-CoV-2 infection. Severe cases of COVID-19 may be driven by metabolic and epigenetic driven mechanisms, including DNA methylation and histone/chromatin alterations. These epigenetic phenomena may respond to enhanced viral replication and mediate persistent long-term infection and clinical phenotypes associated with severe COVID-19 cases and fatalities. Understanding the epigenetic events involved, and their clinical significance, may provide novel insights valuable for the therapeutic control and management of the COVID- 19 pandemic. This review highlights different epigenetic marks potentially associated with COVID-19 development, clinical manifestation, and progression.http://www.frontiersin.org/Immunologyam2022Nuclear Medicin

Maternal consumption of a high-fat diet modulates the inflammatory response in their offspring, mediated by the M1 muscarinic receptor

IntroductionHigh-fat diet (HFD) consumption is associated with various metabolic disorders and diseases. Both pre-pregnancy and maternal obesity can have long-term consequences on offspring health. Furthermore, consuming an HFD in adulthood significantly increases the risk of obesity and metabolic disorders. However, an intriguing phenomenon known as the obesity paradox suggests that obesity may confer a protective effect on mortality outcomes in sepsis. In sepsis, activation of the cholinergic anti-inflammatory pathway (CAP) can help mitigate systemic inflammation. We employed a metabolic programming model to explore the relationship between maternal HFD consumption and offspring response to sepsis.MethodsWe fed female mice either a standard diet (SC) or an HFD during the pre-pregnancy, pregnancy, and lactation periods. Subsequently, we evaluated 28-day-old male offspring. ResultsNotably, we discovered that offspring from HFD-fed dams (HFD-O) exhibited a higher survival rate compared with offspring from SC-fed dams (SC-O). Importantly, inhibition of the m1 muscarinic acetylcholine receptor (m1mAChR), involved in the CAP, in the hypothalamus abolished this protection. The expression of m1mAChR in the hypothalamus was higher in HFD-O at different ages, peaking on day 28. Treatment with an m1mAChR agonist could modulate the inflammatory response in peripheral tissues. Specifically, CAP activation was greater in the liver of HFD-O following agonist treatment. Interestingly, lipopolysaccharide (LPS) challenge failed to induce a more inflammatory state in HFD-O, in contrast to SC-O, and agonist treatment had no additional effect. Analysis of spleen immune cells revealed a distinct phenotype in HFD-O, characterized by elevated levels of CD4+ lymphocytes rather than CD8+ lymphocytes. Moreover, basal Il17 messenger RNA (mRNA) levels were lower while Il22 mRNA levels were higher in HFD-O, and we observed the same pattern after LPS challenge. DiscussionFurther examination of myeloid cells isolated from bone marrow and allowed to differentiate showed that HFD-O macrophages displayed an anti-inflammatory phenotype. Additionally, treatment with the m1mAChR agonist contributed to reducing inflammatory marker levels in both groups. In summary, our findings demonstrate that HFD-O are protected against LPS-induced sepsis, and this protection is mediated by the central m1mAChR. Moreover, the inflammatory response in the liver, spleen, and bone marrow-differentiated macrophages is diminished. However, more extensive analysis is necessary to elucidate the specific mechanisms by which m1mAChR modulates the immune response during sepsis

Tetralogia de Fallot no Brasil: compreendendo a existência

Introduction: Tetralogy of Fallot involves four specific heart problems. Firstly, there is pulmonary stenosis, characterized by the narrowing of the pathway that carries blood from the heart to the lungs, hindering blood flow. Right ventricular hypertrophy is another characteristic, where the muscle of the right ventricle of the heart becomes thicker due to increased workload caused by pulmonary stenosis. Methodology: The present study adopted a descriptive epidemiological approach with the aim of analyzing cases of Tetralogy of Fallot among live births in Brazil from 2012 to 2021. Data collection utilized the Live Birth Information System (SINASC), made available by DATASUS. Results: In the group of individuals born with Tetralogy of Fallot, the analysis of variables reveals valuable information about demographic characteristics and perinatal conditions. Regarding the "Race/Ethnicity" variable, out of the 943 cases registered, 588 (62.35%) were classified as white, 51 (5.41%) as black, 10 (1.06%) as yellow, 267 (28.31%) as brown, and 27 (2.86%) had race/ethnicity recorded as unknown. Conclusion: A profound understanding of congenital heart diseases not only saves lives but also significantly improves the quality of life for affected individuals.Introdução: A Tetralogia de Fallot envolve quatro problemas cardíacos específicos. Em primeiro lugar, há a estenose pulmonar, caracterizada pelo estreitamento da via que conduz o sangue do coração para os pulmões, dificultando o fluxo sanguíneo. A hipertrofia ventricular direita é outra característica, onde o músculo do ventrículo direito do coração torna-se mais espesso devido ao aumento da carga de trabalho provocado pela estenose pulmonar. Metodologia: O presente estudo adotou uma abordagem epidemiológica descritiva com o objetivo de analisar os casos de Tetralogia de Fallot entre os nascidos vivos no Brasil no período de 2012 a 2021. Para a coleta de dados, utilizou-se o Sistema de Informações sobre Nascidos Vivos (SINASC), disponibilizado pelo DATASUS Resultado: No grupo de nascidos com Tetralogia de Fallot, a análise das variáveis revela informações valiosas sobre características demográficas e condições perinatais. Em relação à variável "Cor/Raça", dos 943 casos registrados, 588 (62,35%) eram classificados como brancos, 51 (5,41%) como pretos, 10 (1,06%) como amarelos, 267 (28,31%) como pardos, e 27 (2,86%) tiveram a cor/raça registrada como ignorada Conclusão: A compreensão profunda das cardiopatias congênitas não apenas salva vidas, mas também melhora significativamente a qualidade de vida dos indivíduos afetados

Butyrate Protects Mice from Clostridium difficile-Induced Colitis through an HIF-1-Dependent Mechanism

Antibiotic-induced dysbiosis is a key factor predisposing intestinal infection by Clostridium difficile. Here, we show that interventions that restore butyrate intestinal levels mitigate clinical and pathological features of C. difficile-induced colitis. Butyrate has no effect on C. difficile colonization or toxin production. However, it attenuates intestinal inflammation and improves intestinal barrier function in infected mice, as shown by reduced intestinal epithelial permeability and bacterial translocation, effects associated with the increased expression of components of intestinal epithelial cell tight junctions. Activation of the transcription factor HIF-1 in intestinal epithelial cells exerts a protective effect in C. difficile-induced colitis, and it is required for butyrate effects. We conclude that butyrate protects intestinal epithelial cells from damage caused by C. difficile toxins via the stabilization of HIF-1, mitigating local inflammatory response and systemic consequences of the infection
