Immunological Characteristics between αß TDC and γδ TDC Cells in the Spleen of Breast Cancer-Induced Mice

Abstract Objective To evaluate the antitumoral role of γδ TDC cells and αβ TDC cells in an experimental model of breast cancer. Methods Thirty female Balb/c mice were divided into 2 groups: control group (n=15) and induced-4T1 group (n=15), in which the mice received 2 x 105 4T1 m...

CD4+CD69+ T cells and CD4+CD25+FoxP3+ Treg cells imbalance in peripheral blood, spleen and peritoneal lavage from pristane-induced systemic lupus erythematosus (SLE) mice

Adv Rheumatol; 59 (), 2019
Abstract Background: Adaptive immune cells, including CD4+CD69+ and CD4+CD25+FoxP3+ regulatory T (Treg) cells, are important for maintaining immunological tolerance. In human systemic lupus erythematosus (SLE), CD4+CD25+FoxP3+ Treg cells are reduced, whereas CD69 expression is increased, resulting in a ...

Humoral and cellular immune response of mice challenged with Yersinia pestis antigenic preparations

Braz. j. infect. dis; 21 (6), 2017
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 ind...

BJ-1108, a 6-Amino-2,4,5-trimethylpyridin-3-ol analogue, regulates differentiation of Th1 and Th17 cells to ameliorate experimental autoimmune encephalomyelitis

Biol. Res; 50 (), 2017
BACKGROUND: CD4+ T cells play an important role in the initiation of an immune response by providing help to other cells. Among the helper T subsets, interferon-γ (IFN-γ)-secreting T helper 1 (Th1) and IL-17-secreting T helper 17 (Th17) cells are indispensable for clearance of intracellular as well as ...

Síndrome de falla multiorgánica secundario a hematoma esplénico por Plasmodium vivax

Infectio; 18 (3), 2014
Los cuadros de falla orgánica múltiple y mortalidad secundarios a Plasmodium vivax son escasos. Generalmente esta infección es considerada un enfermedad de curso benigno. El compromiso esplénico con la formación de hematoma es una complicación poco frecuente por este parásito pero, al presentarse,...

Citoquinas inducidas por la inmunización experimental antitetánica. Efecto de la formulación vacunal
[Cytokines induced by experimental anti-tetanus immunization. Vaccine formulation effect]

Medicina (B.Aires); 62 (2), 2002
Several factors are involved in the selective activation of T helper 1 or T helper 2 cells, such as the type of antigen-presenting cells involved in the immune response and the different physical characteristics of antigens. The aim of this work was to evaluate if adding other antigens to tetanus toxoid ...

Análisis peptídico de las proteínas Ro (SSA) y La (SSB)
Peptide analysis of proteins (RO) (SSA) and LA (SSB)

Rev. mex. reumatol; 9 (2), 1994
Se obtuvo extracto total de bazo humano (EBH), purificado por cromatografía de intercambio iónico (DEAE) y filtración molecular; la actividad biológica de las proteínas Ro y La en cada uno de los pasos de purificación fue determinada por pruebas de precipitación en gel e inmunoelectrotransferencia...

Clonación molecular de Ro/SSA de 60 kD

Rev. mex. reumatol; 8 (3), 1993
Se identificaron 12 clonas del cDNA que codifica para el antígeno Ro de 60 KD, utilizando una biblioteca de cDNAs de bazo humano normal insertada en fagos gt11, sus productos de traducción inmovilizados en filtros recombinantes fueron reconocidos exclusivamente por un suero anti-Ro; otros sueros con di...
