Granulated metrial gland (GMG) cells are NK cells that proliferate and differentiate within the murine uterus during pregnancy. They have been predicted to play important roles in nurturing the embryo, normal placentation, and uterine tissue remodeling. GMG cell differentiation is manifested by the accumulation of the cytolytic mediators, perforin, granzyme A, and granzyme B, within cytoplasmic...

Recently, it has been reported that human B cells express and secrete the cytotoxic protease granzyme B (GrB) after stimulation with IL-21 and BCR cross-linking. To date, there are few clues on the function of GrB in B cell biology. As experimental transgenic murine systems should provide insights into these issues, we assayed for GrB in C57BL/6 B cells using an extensive array of physiological...

Background: The most common histologic type of cervical cancer is squamous cell carcinoma (SCC), with the risk recurrence depending on immune surveillance granzyme-B markers, and tumor infiltrating lymphocytes (TIL) an immunological determinant associated a better prognosis. Granzyme-B produced by TIL. study was aimed to prove difference in expression SCC epithelial cells dysplasia precancerous...

Virus-specific CD8+ T cells are critical for the control of acute Friend virus (FV) infections, but are rendered impotent by CD4+ regulatory T cells during the chronic phase of infection. The current study examines this CD8+ T-cell dysfunction by analyzing the production and release of cytolytic molecules by CD8+ T cells. CD8+ T cells with an activated phenotype (CD43+) from acutely infected mi...

background: studies on efficacy of various vaccines that prevent or reduce the primary and recurrent hsv-1 infection have demonstrated the importance of cellular immunity for protection against the infection. we previously used dna vaccination to induce cellular immunity against hsv-1 infection in mice. objective: the aim of our study was to evaluate the effect of light, a member of tnf super f...

We previously identified a subpopulation of monocyte/macrophage lineage cells expressing both CD4 and CD8. This subpopulation was expanded in rat peripheral blood and spleen after immunization with adjuvants containing killed tuberculosis germs. CD4+CD8+ monocytes/macrophages obtained from preimmunized rats exhibited a Th1-type cytokine/chemokine profile, expressed high levels of Fas ligand, pe...
