Abstract:
Failure of the immune system to recognize and eradicate tumor cells has deadly consequences. It is possible that the normal host response to the inflammatory environment created by many cancers - the body's natural attempt at wound repair and restoration of tissue integrity - is one of counter-regulation that paradoxically favors tumor growth. A physiologic condition where this situation is favorable (and even required) is that of normal pregnancy, where blastocyst implantation creates endometrial inflammation, and the maternal response in turn supports angiogenesis and tolerance required for placentation. Lack of such inflammation and resultant maternal immunologic engagement can lead to serious pregnancy complications including fetal loss, highlighting how important the fetomaternal immunologic dialogue is for survival. Here, we describe how the dynamics of fetomaternal tolerance can help disentangle complex cancer/host immunologic interactions and provide new avenues for immunologic reconstitution in patients with cancer.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

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.

Cytotoxic T Cells-mediated Immune Response
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
