1. Update on the pathogenesis of vitiligo
Abstract Vitiligo is a complex disease whose pathogenesis results from the interaction of genetic components, metabolic factors linked to cellular oxidative stress, melanocyte adhesion to the epithelium, and immunity (innate and adaptive), which culminate in aggression against melanocytes. In vitiligo, melanocytes are more sensitive to oxidative damage, lead

2. Innate immunity gene expression profiles in conjunctival membrane biopsies from Amazonian buffalo
RESUMO A produção de búfalos domésticos desempenha um papel economicamente importante na Amazônia brasileira, mas eles são suscetíveis a muitas doenças favorecidas pelo clima tropical e habitats inundados anualmente, incluindo doenças oculares. Nesse contexto, é importante selecionar genótipos que maximizem a imunidade ocular inata em rebanhos ama

3. 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

4. Immune system: development and acquisition of immunological competence
Abstract Objectives: To describe the ontogeny of the immune system and the adaptive mechanisms of the immune system in the neonatal period, with an emphasis on transplacental antibody transport and breastfeeding. Source of data: Non-systematic literature review in the PubMed database. Summary of the findings: The last two decades have witnessed a great ad

5. Plasmacytoid dendritic cells in dermatology,
Abstract Plasmacytoid dendritic cells are part of the dendritic cells family and are a relevant link between innate and adaptive immunity. They are the most potent producers of type 1 interferon, generating antiviral response, stimulating macrophages and dendritic cells and inducing activation and migration of natural killer cells. Plasmacytoid dendritic cel

6. Differential expression of T helper cytokines in the liver during early pregnancy in sheep
Abstract Liver plays important roles in the innate and adaptive immunity, and contributes to the maternal immune adjustments during pregnancy in mice and rats. T helper 1 (Th1) and Th2 cytokines are related to immune response. However, expression of Th1 and Th2 cytokines in maternal livers is unclear during early pregnancy in sheep. In this study, livers wer

8. The Role of ß-Mannanase (Hemicell) in Improving Poultry Productivity, Health and Environment
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nu

9. Micronutrients: Speculation on Inborn Errors, Nutrigenomics, Evolution, the Microbiome, and Nutritional Immunity
Abstract Many micronutrients or cofactors derived from micronutrients are highly reactive, hence their role in catalysis of reactions by enzymes. The concentration of cofactors has to be kept low to avoid unwanted reactions while allowing them to bind to the (apo)enzymes that need them. A new disorder causing B6-responsive epilepsy (proline synthetase cotran

10. Phenoloxidase activity and haemolymph cytology in honeybees challenged with a virus suspension (deformed wings virus DWV) or phosphate buffered suspension (PBS)
RESUMO: O sistema imune inato das abelhas consiste principalmente em peptídeos antimicrobianos, imunidade celular e melanização. Para investigar a resposta imune das abelhas a estressores imunológicos, foram testados três graus de estresse. Abelhas recém-emergidas naturalmente infectadas por DWV foram coletadas de um apiário livre de Varroa e dividid

11. Modelos de inmunidad en estudiantes universitarios: su evolución como resultado de un proceso de enseñanza
Abstract The study of the evolution of the conceptual models of students is a topic of current importance in the didactics of science. Initial studies in the field of modeling were oriented toward describing the models of students and teachers and professors in different fields of knowledge with important results in didactics. Today, and particularly in this

12. Innate immunity and HPV: friends or foes
Most human papillomavirus infections are readily cleared by the host immune response. However, in some individuals, human papillomavirus can establish a persistent infection. The persistence of high-risk human papillomavirus infection is the major risk factor for cervical cancer development. These viruses have developed mechanisms to evade the host immune sy
