T lymphocytes are often induced naturally in melanoma patients and infiltrate tumors. Given that γδ T cells mediate antigen-specific killing of tumor cells, we studied the representation and the in vitro cytokine production and cytotoxic activity of tumor infiltrating γδ T cells from 74 patients with primary melanoma. We found that γδ T cells represent the(More)
Molluscum Contagiosum (MC) virus, a DNA Poxvirus, is responsible for benign infection of the skin epidermal layer and mucous membranes named MC. The lesions are small papules with typical central depressions or umbilications, that contain a waxy, curd-like core. The condition is most common in children, but during the last 25 years has become more common in(More)
