1. 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

2. Os coletivos da Covid-19
RESUMO Ao estudar um fenômeno que atinge a população de diversos continentes, cuidamos de coletivo de pessoas. A pandemia que assola a humanidade é pouco conhecida. Buscando entendê-la, aparecem outros coletivos no discurso: coletivo do pensamento, aglomeração, rede, teste, UTI, rebanho, comboio. Na análise desses coletivos, buscamos elucidar controv

3. Evaluation of pathogen P21 protein as a potential modulator of the protective immunity induced by Trypanosoma cruzi attenuated parasites
BACKGROUND TcP21 is a ubiquitous secreted protein of Trypanosoma cruzi and its recombinant form (rP21) promotes parasite cell invasion and acts as a phagocytosis inducer by activating actin polymerisation in the host cell. OBJECTIVE Our goal was to evaluate if the additional supplementation of rP21 during a prime/boost/challenge scheme with T. cruzi TCC

4. 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

5. Innate immunity and effector and regulatory mechanisms involved in allergic contact dermatitis
Abstract: Skin's innate immunity is the initial activator of immune response mechanisms, influencing the development of adaptive immunity. Some contact allergens are detected by Toll-like receptors (TLRs) and inflammasome NLR3. Keratinocytes participate in innate immunity and, in addition to functioning as an anatomical barrier, secrete cytokines, such as TN

6. Analysis of CD57+ natural killer cells and CD8+ T lymphocytes in periapical granulomas and radicular cysts
Abstract: The aim of this study was to compare the number of CD57+ natural killer (NK) cells and CD8+ T lymphocytes between periapical granulomas (PGs) and radicular cysts (RCs). Twenty-fives cases of PGs and 25 of RCs were submitted to histological analysis and immunohistochemistry using anti-CD57 and anti-CD8 biomarkers. Positive cells were counted in 10 f

7. Paths to the discovery of antivenom serotherapy in France
Abstract The current study presents a descriptive chronological survey of the articles published by Césaire Auguste Phisalix and Albert Calmette on snake poison, with the aim of shedding a light on the areas of research and reasoning followed by these scientists, leading up to their simultaneous discovery of antivenom serotherapy in 1894. The path taken by

8. Assessing bovine babesiosis in Rhipicephalus (Boophilus) microplus ticks and 3 to 9-month-old cattle in the middle Magdalena region, Colombia
Babesia sp. is a protozoan hemoparasite that affects livestock worldwide. The Colombian Middle Magdalena is an enzootic region for babesiosis, but there is no previous research providing detail on its transmission cycle. This study aims to assess some Babesia sp. infection indicators in cattle and ticks from the area, by using direct microscopic and molecula

9. Vaccines for preventing herpes zoster in older adults
BACKGROUND:Herpes zoster or, as it is commonly called, 'shingles' is a neurocutaneous disease characterised by the reactivation of varicella zoster virus (VZV), the virus that causes chickenpox, which is latent in the dorsal spinal ganglia when immunity to VZV declines. It is an extremely painful condition which can often last for many weeks or months, impai

10. Immunological characteristics of mesenchymal stem cells
Although bone marrow is the main source, mesenchymal stem cells have already been isolated from various other tissues, such as the liver, pancreas, adipose tissue, peripheral blood and dental pulp. These plastic adherent cells are morphologically similar to fibroblasts and have a high proliferative potential. This special group of cells possesses two essenti

11. Condicionantes sociais na delimitação de espaços endêmicos de hanseníase / Social conditions in the delimitation of areas endemic for leprosy
INTRODUÇÃO: A hanseníase é uma doença infecciosa crônica granulomatosa, cujo agente etiológico é uma bactéria de vida intracelular obrigatória, o Mycobacterium leprae, que tem no homem seu principal reservatório. A doença possui distribuição universal, predominando atualmente, em latitudes tropicais e tem sido enquadrada entre as enfermidades n

12. Cinética do cultivo de Neisseria lactamica em biorreator. / Bioreactor cultivation kinetics of Neisseria lactamica.
Neisseria lactamica está envolvida na aquisição da imunidade natural contra Neisseria meningitidis, causadora da doença meningocócica. Vesículas de membrana externa (OMV) de N. lactamica são antígenos potenciais contra N. meningitidis. Analisou-se a cinética de biomassa, de produção de OMV, da fonte de carbono (lactato), e dos metabólitos, para m
