Melasma is a characteristic pattern of hyperpigmentation, occuring primarily on the forehead, cheeks, and chin in a mask-like distribution. Pigmentation is regulated by complex processes ranging from the molecules, which are relevant to melanin synthesis to symbiotic interactions with keratinocytes of the skin as a fully integrated system. Etiologic factors associated with melasma are genetic p…

T-lymphoxytes are the most important component of the immune response to control recurent infections. T-lumphocutes of CD4+ and CD8+ bearing T-cells can kill HSV intected host cells. The relation between apecific T-cells responses and severity of HSV disease of HSV disease have not been consistently detcted. Interaction between T-cells responses and HSV and host immunity. Reactivation can resul…
