Kupffer Cells Mediate Systemic Antifungal Immunity

Kupffer cells mediate leptin-induced liver fibrosis.

BACKGROUND & AIMS Leptin has profibrogenic effects in liver, although the mechanisms of this process are unclear. We sought to elucidate the direct and indirect effects of leptin on hepatic stellate cells (HSCs). METHODS HSCs from Sprague-Dawley rats were exposed to leptin and expression of collagen-I, tissue inhibitor of matrix metalloproteinases-1 (TIMP1), transforming growth factor beta1 (...

Natural Killer Cells in Antifungal Immunity

Invasive fungal infections are still an important cause of morbidity and mortality in immunocompromised patients such as patients suffering from hematological malignancies or patients undergoing hematopoietic stem cell transplantion. In addition, other populations such as human immunodeficiency virus-patients are at higher risk for invasive fungal infection. Despite the availability of new anti...

Dendritic cells in antifungal immunity and vaccine design.

Life-threatening fungal infections have increased in recent years while treatment options remain limited. The development of vaccines against fungal pathogens represents a key advance sorely needed to combat the increasing fungal disease threat. Dendritic cells (DC) are uniquely able to shape antifungal immunity by initiating and modulating naive T cell responses. Targeting DC may allow for the...
