Numerous studies have demonstrated that ultraviolet B (UVB) irradiation has profound effects on the skin and systemic immune systems. Because many of the effects of UVB result in suppression of contact sensitivity responses and because IL-10 induces

APC dysfunction may be important in immune dysregulation associated with HIV disease. Langerhans cells, epidermal APC, can be infected with HIV, although their function in HIV-infected persons has not been studied. Therefore, we studied the immunolog

Although protein-derived nominal Ags have, in many instances, been precisely determined, the epitopes recognized by hapten-specific CD4+ T cells responsible for contact sensitization have not been defined. To better understand the nature of the preci

Epidermal Langerhans cells are derived from cells of bone marrow origin and, as the primary APC population in the skin, are responsible for initiation of many immune responses. Consequently, cell surface expression of MHC Ags by Langerhans cells is c

Heat-stable antigen (HSA), expressed by activated B cells, has been described as a costimulatory molecule for CD4+ T cells. Because epidermal Langerhans cells (LC) are known to express HSA, we determined whether LC HSA also served as a costimulator o

IL-10 is a product of activated keratinocytes and is released during the induction phase of contact sensitivity. As IL-10 effects have been described as being mediated by APC, we investigated effects of IL-10 on epidermal Langerhans cells (LC), the r

Langerhans cells (LC) are Ag-presenting cells required for induction of primary immune responses in skin. After activation by Ag, LC express increased levels of MHC class II Ag, exhibit increased accessory cell activity, and migrate to regional lymph

It has previously been demonstrated that the epidermis is a rich source of proinflammatory cytokines and growth factors and that complex interactions between these factors may affect inflammatory responses in skin. To investigate whether IL-10 (cytok

Because our previous in vitro studies of hapten-modified Ia+ keratinocytes (KC) indicated that these cells induced anergy in Ag-specific Th1 cells, we assayed such cells for their ability to induce unresponsiveness in an in vivo animal model system o

There is controversy regarding the ability of short term (2 to 3 days) cultured epidermal Langerhans cells (cLC) to process and present intact protein Ag to primed T cells. Some studies have shown that cLC are potent APC for both haptens and intact p
