Background: 17β-estradiol (E2) has been known to modulate immune response. Recent studies indicate that E2 at pregnancy level plays a role in regulating T cell response. Objective: To investigate the optimum dose of E2 (from 10-9 to 10-7 M) in mediating the generation of regulatory T cells (Tregs), using naïve human CD4+ T cells from healthy women. Methods: Naïve peripheral T cells were purifie...
Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...
Mesenchymal Stem Cells (MSCs) are well known as the regulator of the immune system. These multipotent non-hematopoietic progenitor cells have been originally isolated from bone marrow, and later on found in several other tissues, such as skeletal muscle, umbilical cord blood, adipose and fetal liver tissues. Immunomodulatory effects of MSCs on a variety of immune cells such as T and B lymphocyt...
