13. 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

14. Subsets of T lymphocytes in the lesional skin of pityriasis rosea
Abstract: Background: Pityriasis rosea is a common papulosquamous disorder. However, its etiology and pathogenesis remain unclear. Objective: We investigate the types of inflammatory cells infiltrating the lesional skin of pityriasis rosea and demonstrate whether T-cell-mediated immunity is involved in the pathogenesis of this condition or not. Methods: T

15. β-Glucan of Candida albicans Cell Wall Extract Inhibits Salmonella Typhimurium Colonization by Potentiating Cellular Immunity (CD8 + and CD4 + T Cells)
Abstract INTRODUCTION: Antimicrobial resistance has been reported in the drugs used for the treatment of typhoid fever. The immunomodulatory substance β-glucan can be used as an alternative therapy as it potentiates host immunity. The aims of this study are to observe the effect of Candida albicans cell wall (CCW) extract towards host immunity (TCD8+ and T

16. Use of domperidone in canine visceral leishmaniasis: gaps in veterinary knowledge and epidemiological implications
A pivotal strategy to decrease the risk of visceral leishmaniasis in humans is to control the infection and disease progression in dogs, the domestic reservoir of Leishmania infantum (L. chagasi). Immunotherapy is a viable approach to treat sick dogs because cell-mediated immunity is the principal defense mechanism against L. infantum. Domperidone is an immu

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. Perspectives for cancer immunotherapy mediated by p19Arf plus interferon-beta gene transfer
While cancer immunotherapy has gained much deserved attention in recent years, many areas regarding the optimization of such modalities remain unexplored, including the development of novel approaches and the strategic combination of therapies that target multiple aspects of the cancer-immunity cycle. Our own work involves the use of gene transfer technology

19. Prevalence of anemia in schools of the metropolitan region of Curitiba, Brazil
ABSTRACT Background: Anemia during childhood is one of the biggest public health problems worldwide, including Brazil. Insufficient or abnormal production of hemoglobin, loss of iron and excessive destruction of red blood cells are the most common causes of anemia. Among the reasons of anemia, iron deficiency accounts for 50% of anemia cases in developing c

20. Epididymo-orchitis caused by Histoplasma capsulatumin a Colombian patient
Abstract Although histoplasmosis is generally a self-limited disease, disseminated infection can occur in patients lacking effective cell-mediated immunity, reaching virtually every organ, even the genitourinary tract in rare cases. We report a case of epididymo-orchitis in an immunocompetent 38-year-old bricklayer from the rural area of Villeta, Cundinamarc

21. Humoral and cellular immune response of mice challenged with Yersinia pestis antigenic preparations
ABSTRACT Objectives: The plague, which is an infectious disease caused by Yersinia pestis, still threatens many populations in several countries. The worldwide increase in human plague cases and the potential use of the bacteria as a biological weapon reinforce the need to study the immunity that is induced by potential vaccine candidates. To determine the

22. Combined genotypes of the MBL2 gene related to low mannose-binding lectin levels are associated with vaso-occlusive events in children with sickle cell anemia
Abstract Sickle cell anemia (SCA) presents heterogenous clinical manifestations that cannot be explained solely by alterations to hemoglobin (Hb); other components such as endothelial adhesion, thrombosis and inflammation may be involved. The mannose-binding lectin (MBL) has an important role in innate immunity and inflammatory diseases. In this report, we d

23. Translational control in plant antiviral immunity
Abstract Due to the limited coding capacity of viral genomes, plant viruses depend extensively on the host cell machinery to support the viral life cycle and, thereby, interact with a large number of host proteins during infection. Within this context, as plant viruses do not harbor translation-required components, they have developed several strategies to s

24. Infectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines
ABSTRACT The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed a
