[Immunologic aspects of infections with papillomaviruses. Prospects for a vaccine]
Abstract:
Human papillomaviruses induce benign or malignant epithelial proliferations in both skin or mucosa and are involved in the development of anogenital cancer. One can consider two approaches towards vaccine development: prevention of infection by prophylactic induction of virus neutralizing antibodies or therapeutic vaccination which would lead to regression of already existing lesions. Neutralizing antibodies are directed against 3-dimensional structures on intact virions. Such antibodies which are protective in model systems can be induced safely by DNA-free "virus-like-particles". These constructs are candidates for a prophylactic vaccine. A further approach to optimize the vaccination strategy concentrates on immunotherapy of precancerous or malignant lesions by induction of a specific cell-mediated immune response. Hypothetically the transforming papillomavirus proteins which are expressed in basal layers of the epidermis could be used as a therapeutic vaccine in the form of synthetic peptides.

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...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
