1. Ascaris lumbricoides coinfection reduces tissue damage by decreasing IL-6 levels without altering clinical evolution of pulmonary tuberculosis or Th1/Th2/Th17 cytokine profile
Abstract INTRODUCTION: Immunological control of Mycobacterium tuberculosis infection is dependent on the cellular immune response, mediated predominantly by Th1 type CD4+ T cells. Polarization of the immune response to Th2 can inhibit the host immune protection against pathogens. Patients with tuberculosis coinfected with helminths demonstrate more severe

2. Preservation of cytotoxic granule production in response to mycobacterial antigens by T-lymphocytes from vertically HIV-infected Brazilian youth on effective combined antiretroviral therapy
ABSTRACT Background: HIV infection harms adaptive cellular immunity mechanisms. Long-term virological control by combined antiretroviral therapy (cART) reduces the risk of mycobacterial infections. Thus, we aimed to study cellular responses to mycobacterial antigens in 20 HIV-infected adolescents with at least one year of virological control (HIV-RNA <40 co

3. Immunological response to re-infections with clones of the Colombian strain of Trypanosoma cruzi with different degrees of virulence: influence on pathological features during chronic infection in mice
Re-infections with Trypanosoma cruzi are an aggravating factor for Chagas disease morbidity. The Colombian strain of T. cruzirepresents multiclonal populations formed by clonally propagating organisms with different tropisms and degrees of virulence. In the present study, the influence of successive inoculations with clones of the Colombian strain, exhibitin

4. Revisiting the Rich's formula: an update about granulomas in human tuberculosis
The formula proposed by Rich in 1951 explained the formation in a tuberculous lesion in a period that was unknown cellular functions, cytokines and other immunological aspects involved in granuloma formation by tuberculosis; its components are assembled conceptually to explain the pathogenic mechanisms involved in the granulomatous lesion in tuberculosis. In

5. Atividade imunomoduladora da ouabaína no processo inflamatório agudo / OUABAIN IMMUNOMODULATORY ACTIVITY IN THE ACUTE INFLAMMATORY PROCESS.
Ouabain (OUA), a potent inhibitor of the Na+,K+-ATPase pump, was identified as an endogenous substance of human plasma. In recent years, ouabain was shown to affect various immunological processes. Mechanisms that involve cellular differentiation, proliferation, activation and migration, as well as inflammatory mediators release, are activated during inflamm

6. Uncaria tomentosa: POSSÍVEL USO COMO ADJUVANTE NO TRATAMENTO DO CÂNCER CÓLON RETAL / Uncaria tomentosa: POSSIBLE USE AS AN ADJUVANT IN THE TREATMENT OF COLORECTAL CANCER
Reports of the use of cat s claw (Uncaria tomentosa) in patients with cancer, in conjunction with traditional therapies such as chemotherapy and radiotherapy, show decrease in adverse effects to these therapies (such as hair loss, weight loss, nausea, secondary infections, and skin problems). Subsequent research showed that cat s claw may help in the restora

7. Produção e caracterização do anticorpo monoclonal aDEC205 acoplado a proteína MSP-1 (19) de Plasmodium chabaudi. / Production and characterization of a monoclonal antibody aDEC205 coupled to MSP-1(19) protein from Plasmodium chabaudi.
Despite the strong activation of the immune system that occurs during infection by Plasmodium, the immunological memory to infection is restricted to patients residing in endemic areas. Thus it is important to the generation of methods to induce an effective immune response against the parasite. In this context, the targeting of antigens to the central cells

8. Resposta imune de suínos imunizados pela via nasal com proteínas de roptrias do Toxoplasma gondii
Toxoplasma gondii is an obligate intracellular parasite that infects a wide range of hosts including human beings. Herbivores are the main domestic infection sources for humans, and pork is considered the most important route of transmission. Recent decades have witnessed a great increasing in the number of technologies and immunological research to produce

9. Tuberculin skin testing in HIV-infected patients in Campo Grande, Mato Grosso do Sul State, Brazil
A cross-sectional study on HIV/AIDS was carried out in 108 outpatients from the university hospital of the Federal University of Mato Grosso do Sul, Campo Grande, Brazil, from July to December 2008, to investigate latent tuberculosis infection using the tuberculin skin test (TST). The prevalence of positive results was 13.9%. The CD4+ T cell count (p = 0.091

10. Immunological response to equine chorionic gonadotropin (eCG) in Bos taurus and Bos indicus heifers / Resposta imunológica contra gonadotrofina coriônica equina (eCG) em novilhas Bos taurus e Bos indicus
O presente trabalho foi realizado em duas etapas experimentais. O objetivo do Experimento 1 foi avaliar o perfil de produção de anticorpos anti-eCG em novilhas Bos taurus e Bos indicus tratadas uma, duas ou três vezes, com 400 e com 2000UI de eCG. O experimento foi realizado em duas réplicas com o mesmo desenho experimental, porém com padrões raciais d

11. Immunological imbalance between IFN-³ and IL-10 levels in the sera of patients with the cardiac form of Chagas disease
The immune response is crucial for protection against disease; however, immunological imbalances can lead to heart and digestive tract lesions in chagasic patients. Several studies have evaluated the cellular and humoral immune responses in chagasic patients in an attempt to correlate immunological findings with clinical forms of Chagas disease. Moreover, im

12. Mecanismos inflamatórios e imunológicos na síndrome de Down / Inflammatory and immunological mechanism in Downs syndrome
In recent years there has been an increase in life expectancy of individuals with Down´s syndrome (DS), with death causes differ from the general population. Some studies have shown that the immune response differs throughout life with changes related to aging. The RCAN1 gene (regulator of calcineurin type 1), located in the q22.12 region of chromosome 21 i
