1. Immunological deficiencies: more frequent than they seem to be
Abstract Objective: A review article was carried out, addressing the clinical and epidemiological characteristics of immune system deficiencies, which are associated with or predispose to recurrent infectious processes, autoimmune diseases, auto inflammatory diseases, or neoplasms, and which are classified as inborn errors of immunity (IEI) and secondary im

2. Immunodeficiencies: non-infectious manifestations
Abstract Objectives: Classical immunodeficiencies are mainly characterized by infectious conditions. In recent years, manifestations related to allergy, inflammation, autoimmunity, lymphoproliferation, and malignancies related to this group of diseases have been described. The text intends to make an update on the non-infectious manifestations of the primar

3. Corticotropin-releasing factor receptor signaling and modulation: implications for stress response and resilience
Abstract Introduction In addition to their role in regulation of the hypothalamic-pituitary-adrenal-axis, corticotropin-releasing factor (CRF) and its related peptides, the urocortins, are important mediators of physiological and pathophysiological processes of the central nervous, cardiovascular, gastrointestinal, immune, endocrine, reproductive, and skin

4. Resveratrol and resveratrol-hydroxypropyl-β-cyclodextrin complex recovered the changes of creatine kinase and Na+, K+-ATPase activities found in the spleen from streptozotocin-induced diabetic rats
Abstract: Type 1 diabetes (T1D) is the result of the selective destruction of the pancreatic β-cells by T cells of the immune system. Although spleen is a secondary lymphoid organ, it is also involved in the T1D pathogenesis. However, the alterations in a variety of cellular processes of this disease need to be further understood. We aimed to analyze the be

5. Secondary hemophagocytic syndrome after renal transplantation: two case-reports
RESUMO A síndrome hemofagocítica (SHF) ou linfo-histiocitose hemofagocítica é uma condição infrequente e subdiagnosticada que tem por base a ativação excessiva da resposta imune, resultando em fagocitose das células do sangue. Após o transplante renal (TxR), a SHF é habitualmente secundária (ou reativa) a processos infecciosos e neoplásicos, cul

6. Repercussions of inborn errors of immunity on growth
Resumo Objetivos: Revisão da literatura sobre as repercussões dos diferentes erros inatos da imunidade sobre o crescimento, chamar a atenção para o diagnóstico desse grupo de doenças em pacientes que apresentem desordens do crescimento, assim como permitir que se identifiquem as diferentes causas de alterações do crescimento em pacientes com erros i

7. Host response mechanisms in periodontal diseases
Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia and Treponema denticola that trigger innate, inflammatory, and adaptive immune respon

8. Anti-inflammatory and anti resorptive bone effects of minocycline in periodontal disease induced in normal and diabetic rats. / Efeitos anti-inflamatÃrios e antirreabsortivo Ãsseo da minociclina na doenÃa periodontal induzida em ratos diabÃticos e normais.
The immune/inflammatory response has a key role in the periodontal disease (DP) whose progression results from an imbalance between periodontopathogenic microorganisms and the host response. This leads to the production and release of inflammatory mediators and tissue damage. DP is considered the sixth complication in diabetes. Furthermore, diabetes mellitus

9. Simulação Computacional e Análise de um Modelo Fenotípico de Evolução Viral. / Computer Simulation and Analysis of a Phenotypic Model of Viral Evolution
A large amount of viruses of medical importance such as HIV, respiratory syncytial virus, the hepatitis C virus, influenza A (H1N1) and polio virus, has RNA genome. These viruses exhibit extremely high mutational rate, fast replicative kinetics, large population of particles and high genetic diversity. Manifested during the infectious process, these features

10. Molecular epidemiology and evolution of avian infectious bronchitis virus
Mutation and recombination processes are involved in the genetic and phenotypic variations of RNA viruses, leading to the emergence of new variant strains, and give rise to virus population diversity to be modeled by the host, particularly by the immune system, as occurred with infectious bronchitis virus (IBV) in chickens. The consequence is a continuous em

11. Cardiac gene expression and systemic cytokine profile are complementary in a murine model of post-ischemic heart failure
After myocardial infarction (MI), activation of the immune system and inflammatory mechanisms, among others, can lead to ventricular remodeling and heart failure (HF). The interaction between these systemic alterations and corresponding changes in the heart has not been extensively examined in the setting of chronic ischemia. The main purpose of this study w

12. Modulação de eventos da imunidade humoral e celular por venenos brutos e componentes dos venenos de Bothrops jararacussu e Bothrops pirajai / Modulation of events of humoral and cellular immunity by crude venom and components of Bothrops jararacussu and Bothrops pirajai
Snakes of the genus Bothrops are responsible for 90% of snakebites in Brazil. Their venoms cause local effects in humans and animals, such as hemorrhage, edema, pain and necrosis, characteristic of an inflammatory response. The mechanism is not well defined. These effects are related to the combined action of proteases, substances that induce bleeding and ph
