بررسی تاثیر تجویز لاکتوباسیلوس رامنوسوس (LMG 18243) بر روند رشد سرطان پستان در موشهای inbred BALB/c
Background & Aims: Breast cancer is one of major invasive women cancers. Probiotics are nonpathogenic micro-organisms that have immuno-stimulatory effects. Probiotics can stimulate the systemic immunity beside gut immunity against cancer. This study aimed to evaluate the effects of lactobacillus rhamnosus LMG18243 on breast cancer development in inbred Balb/C mice. Materials & Methods: Ten Ba...
Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study,...
Objectives B cell-mediated immunity can be associated with favorable clinical outcomes in cancer patients. However, the mechanism and features of anti-tumor immune responses are not well understood. In particular, how cells expressing tumor-specific antibodies distributed (in tumor vs. circulation) has been defined. Methods We performed an in-depth analysis cell antibody repertoires derived fro...
objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...
It is widely accepted that cellular immune responses are induced by CD4(+) T helper 1 (Th1) cells secreting interleukin (IL)-2 and interferon (IFN)-gamma. Tumor immunity is often mediated by cytotoxic T lymphocytes (CTLs) whose activation is supported by Th1 cytokines. Since IL-4 directs Th2 development and has been shown to inhibit Th1-dominated responses, we assumed that IL-4-deficient (IL-4(...
Concomitant tumor immunity describes immune responses in a host with a progressive tumor that rejects the same tumor at a remote site. In this work, concomitant tumor immunity was investigated in mice bearing poorly immunogenic B16 melanoma. Progression of B16 tumors did not spontaneously elicit concomitant immunity. However, depletion of CD4(+) T cells in tumor-bearing mice resulted in CD8(+) ...
