1. Leptina: um modulador central das respostas imunes. / Leptin: a central modulator of imune responses.
Leptin is a mediator of both neuroendocrine and immune responses, and has been associated with several autoimmune diseases. Our objective was to study the importance of leptin in modulating the immune response in experimental transplantation, with emphasis on its role in the plasticity of T lymphocytes and dendritic cells (DC). We observed that animals lepti

2. Clinical signs, diagnosis, and case reports of Vaccinia virus infections
Vaccinia virus is responsible for a zoonosis that usually affects cattle and human beings in Brazil. The initial clinical signs of the infection are focal red skin areas, fever, and general symptoms similar to those of a cold. Then, pustules and ulcerated lesions surrounded by edema and erythema follow, as well as local lymphadenopathy that can last for week

3. As contribuições de Alexander Fleming para o estudo da imunologia natural: 1908-1921
On the turn of the twentieth century, several scientists were investigating infectious diseases. The aim of this research is to rebuild the path followed by Alexander Fleming (1881-1955) in his studies on microbiology, from 1908 to 1921, when he identified an enzyme related to the natural immunology of living beings. This dissertation contains an introductio

4. Basophils activation profile and evidence of histamine release factor in Chronic Idiopathic Urticaria / Perfil de ativação de basófilos e evidência de fatores liberadores de histamina na urticária crônica idiopática
INTRODUCTION: Chronic Urticaria is characterized by recurrent, transitory, pruritic and erythematous wheals present for at least six weeks. In most patients the cause is unknown, defined as idiopathic (CIU), however, a sub-group has autoantibodies against the alfa chain of the high affinity IgE receptor (FceRIa) expressed on mast cells and basophils surface

5. Caracterização da resposta inflamatória no enxerto singênico e alogênico em modelo experimental de transplante de pele. / Characterization of the inflammatory response in the syngeneic and allogeneic graft in an experimental model of skin transplantation.
A inflamação é um evento intrínseco ao transplante que é desencadeado após o dano causado pela cirurgia. No presente trabalho realizou-se a caracterização fenotípica e funcional das células inflamatórias presentes no enxerto, após o transplante alogênico ou singênico de pele em camundongos. Os resultados obtidos mostraram diferenças significat

6. Dendritic cells and the 60kDa heat shock protein (Hsp60): strategies for immunoregulation in the mouse immune system / Células dendríticas e a proteína de choque térmico 60KDA (HSP60): estratégias para imunorregulação do sistema imune murino
The induction of tolerance to allotransplant without the help of immunosupressive drugs is one of the major challenges in immunology. Considering the tolerogenic potential of dendritic cells and the immunoregulatory activity of Hsp60, our objective was to determine the capacity of dendritic cells (DCs) of inducing immunoregulation through the interaction wit

7. Effects of chronic and prolonged solar radiation in immunologic system of fishermen from Recife, Brazil / Efeitos da radiação solar crônica e prolongada sobre o sistema imunológico de pescadores do Recife
Introduction: The ultraviolet radiation effects on the human immunological system are highly complex, disturbing some components of immune response. Objective: The objective of this study was to evaluate the clinical, histopathological and immunological effects from solar radiation in male fishermen with more than 10 years of uninterrupted activity. Methods:

9. Humoral immune response characterization of the type V collagen induced scleroderma experimental model / Caracterização da resposta imune em modelo experimental de esclerodermia induzida por colágeno tipo V
Experimental models for human diseases are of utmost importance, since they allow the study of their pathogenesis and therapeutic approach. In this group we can include the experimental model of collagen V-induced scleroderma, in rabbits, with histological alterations (skin, lung and kidney) similar to those observed in humans. Auto-immune diseases have an u

10. Avaliação do BCG como adjuvante na imunoterapia específica para asmáticos / Assessment of BGC as an adjuvant in specific immunotherapy in asthmatic patients
O aumento da prevalência de doenças alérgicas como a asma, tem sido atribuído à falta de estímulos infecciosos. A atopia, que embasa as manifestações alérgicas, caracteriza-se por uma disfunção imune com predomínio da resposta do tipo Th2. Experimentos em modelos animais com micobactérias e seus produtos têm demonstrado resultados promissores n

11. In vivo induction of antigen-specific transplantation tolerance to Qa1a by exposure to alloantigen in the absence of T-cell help.
A goal of transplantation immunology is to be able to induce antigen-specific tolerance in transplant recipients. In the present study we describe an in vivo model of antigen-specific transplantation tolerance to skin allografts using mice congenic at Qa1, a ubiquitously expressed class I-like molecule encoded to the right of H-2D. B6 mice are deficient in Q

12. Aging and Cumulative Inequality: How Does Inequality Get Under the Skin?
Purpose: This article draws from cumulative disadvantage and life course theories to develop a new theory for the social scientific study of aging. Design and Methods: Five axioms of cumulative inequality (CI) theory are articulated to identify how life course trajectories are influenced by early and accumulated inequalities but can be modified by available
