13. Toxoplasma gondii in cetaceans of Brazil: a histopathological and immunohistochemical survey
Resumo Toxoplasmose é uma doença parasitária causada pelo protozoário Toxoplasma gondii. A infecção por T. gondii é uma causa significativa de morbidade e mortalidade, nos cetáceos. Apesar da abrangência mundial e amplo registro de espécies de cetáceos infectadas por T. gondii, informações sobre toxoplasmose em cetáceos do hemisfério sul são

15. The role of GNLY gene polymorphisms in psoriasis pathogenesis
Abstract BACKGROUND: Psoriasis is a systemic inflammatory disorder that involves complex pathogenic interactions between the innate and adaptive immune systems. The most accepted mechanism in the etiopathogenesis of psoriasis is the induction of inflammation with keratinocyte hyperproliferation. Granulysin (GNLY) is a cytolytic antimicrobial peptide (AMP) t

16. Antioxidant and immunomodulatory activities of Oviductus ranae in mice
Oviductus ranae (OR) is a traditional Chinese medicine, which was first recorded in the Compendium of Materia Medica in the Ming Dynasty. OR contains high amounts of proteins and elicits therapeutic effects on neurasthenia, insomnia, and respiratory symptoms, which are related to oxidative stress and immunodeficiency. This study aimed to obtain the potential

17. 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

18. 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

19. Identificação e susceptibilidade de isolados clínicos de Candida spp. para toxinas assassinas
Resumo Embora as infecções invasivas e a mortalidade causada por espécies de Candida estejam aumentando entre pacientes comprometidos, a resistência a agentes antifúngicos comuns também é um problema crescente. Analisamos 60 leveduras isoladas de pacientes com candidíase invasiva utilizando como estratégia PCR/RFLP baseada na região espaçadora tra

20. 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

21. Cytotoxic activity in cutaneous leishmaniasis
Cutaneous leishmaniasis (CL) is a chronic disease caused by species of the protozoan Leishmania and characterised by the presence of ulcerated skin lesions. Both parasite and host factors affect the clinical presentation of the disease. The development of skin ulcers in CL is associated with an inflammatory response mediated by cells that control parasite gr

22. Production and Optimization of Killer Toxin in Debaryomyces hansenii Strains
ABSTRACT Postharvest diseases of fruits and vegetables result in critical losses of production in worldwide. The losses often are caused by fungi and nowadays, most fungal pathogens are controlled by several strategies such as the use of fungicides. However, most of the fungicides are chemical-based compounds and are dangerous to human health and the nature.

23. Imunoterapia com células natural killer: um caminho possível para o tratamento da Leucemia Mielóide Aguda também no Brasil
RESUMO O transplante de células-tronco hematopoéticas (TCTH) alogênico é curativo para leucemia mielóide aguda de risco intermediário e alto. Mesmo com o desenvolvimento de estratégias para minorar a toxicidade do TCTH, este ainda é um tratamento complexo com elevada morbi-mortalidade. O conhecimento sobre o efeito enxerto contra leukemia do TCTH pav

24. Study on the polymorphism of POU1F1 gene in sheep
ABSTRACT In this study, POU1F1 gene polymorphism was detected in five sheep populations (large-tailed Han, small-tailed Han, Yuxi fat-tailed, Lanzhou large-tailed, and Mongolian sheep), using DNA pooling and sequencing, to provide theoretical basis for the breeding of excellent sheep varieties. Three single-nucleotide polymorphism (SNP) loci of POU1F1 gene w
