Protective Efficacy and Pulmonary Immune Response Following Subcutaneous and Intranasal BCG Administration in Mice
Published on: September 19, 2016
The effects of Korean herbal medicine (B.C.L.) on some parameters of immunological response were studied in mice. B.C.L. pretreatment given either intraperitoneally or subcutaneously in a dose of 0.75 mg/mouse did not significantly inhibit lymphocyte transformation induced by concanavalin A. However, B.C.L. pretreatment in a dose of 2.25 mg/mouse was found to reduce significantly both the plaque-forming cells to sheep red blood cells immunisation as well as total spleen cell population. Thus, B.C.L. pretreatment with a higher dose (2.25 mg/mouse) can selectively depress the humoral immune response. It is unclear, however, whether this action is mediated by the parent compound or its metabolites.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
