Background: Small cell lung cancer (SCLC) is characterized by rapid progression and low survival rates. Therefore, novel therapeutic agents are urgently needed for this disease. Capsaicin, the active ingredient of chilli peppers, displays antiproliferative activity in prostate and epidermoid cancer in vitro. However, the anti-proliferative activity of capsaicin has not been studied in human SCLCs. The present manuscript fills this void of knowledge and explores the anti-proliferative effect of capsaicin in SCLC in vitro and in vivo. Methodology/Principal Findings: BrdU assays and PCNA ELISAs showed that capsaicin displays robust anti-proliferative activity in four human SCLC cell lines. Furthermore, capsaicin potently …

In a murine model of autoimmunity targeted against the epidermal cell Ags, Skn, adoptive transfer of Skn-immune T cells to immunosuppressed recipients elicits skin lesions in areas of mild epidermal trauma. In this study, we examined peripheral regulation of Skn-induced autoreactivity disrupted by rendering the mice immunoincompetent. We found that regulation of Skn-directed autoimmunity was restored by cotransfer of normal syngeneic spleen cells at twice the concentration of Skn-immune cells and was evidenced by significantly reduced lesion severity by days 5–7 post-cotransfer compared with animals given injections of Skn-immune cells alone. Enrichment and depletion of normal CD4 or CD8 spleen …
