The development of effective T cell-based immunotherapy for cancer requires the identification of antigens capable of inducing both CTL and T helper immune responses. Although CTLs will participate in the antitumor response mainly by exerting their lytic activity on the tumor cells, helper T lymphocytes will be critical for the induction and maintenance of the CTLs. Thus, effective subunit ther...

The humoral immune response to heterologous erythrocytes requires the cooperation of B lymphocytes and helper T cells. The production of anti-sheep erythrocytes (SRBC) 1 IgG is almost wholly dependent on the activity of T help (reviewed in 1). Helper T cells that recognize the carrier portion of an immunogen have been known for some time (2). More recently evidence has accumulated that other he...

OBJECTIVE Fetal dysregulation of T helper cell pathways may predispose to allergy, as high cord blood T helper 2/T helper 1 ratios have been shown to precede development of allergic diseases. We aimed to determine whether prenatal eicosapentaenoic acid and docosahexaenoic acid supplementation reduces T helper 2 to T helper 1-associated chemokine ratios. We also explored the effect of mode of de...

Recent studies indicate that the lateral subdivision of the central amygdala (CeL) is essential for fear learning. Specifically, fear conditioning induces cell-type-specific synaptic plasticity in CeL neurons that is required for the storage of fear memories. The CeL also controls fear expression by gating the activity of the medial subdivision of the central amygdala (CeM), the canonical amygd...

Efforts to improve melanoma response rates to temozolomide (TMZ) have thus far been unsuccessful. We screened a library of 2,000 marketed drugs and natural products to identify agents with the potential to sensitize melanoma cells to the effects of TMZ. Celastrol (CEL), a natural compound found in the Thunder of God vine, was identified based on its ability to enhance cell death in TMZ-resistan...
