Lipopolysaccharide (LPS) has long been known to enhance innate and adaptive immune responses; however, its extreme toxicity precludes its use in clinical settings. The combined toxicity and adjuvanticity of LPS have contributed to the view that immunological adjuvants need to be highly inflammatory to be maximally effective. Here, we compared the effects of(More)
Vitamin D and its hormonally active metabolite 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] are known to alter several parameters associated with stimulated intestinal Ca2+ transport: levels of calbindin-D28K, tubulin, and endosomal-lysosomal organelles containing Ca2+, and calbindin-D28K. In the present study the as yet unexamined relationship among Ca2+(More)
We describe a method to characterize the effects that immunological adjuvants have on in vivo lymphocyte proliferation at the level of daughter cell accumulation. We used standard 5,6-carboxyfluorescein diacetate succinimidyl ester (CFSE)-labeling techniques to follow T cells through multiple rounds of division in experimentally treated mice and measured(More)
The NFkappaB factor Bcl-3 influences the survival of T cells when they are activated to take part in immune responses. Because treatment of mice with adjuvant results in the increased expression of Bcl-3 in T cells, where it has survival-promoting effects, Bcl-3 may be an important, limiting factor that is supplied to T cells only when they are contributing(More)
Immunological adjuvants increase the clonal burst size of antigen-specific T cell populations by mechanisms that remain incompletely understood. Using the DO11.10 adoptive transfer system to study peptide-stimulated T cell responses, we found that TLR agonist treatment increased the extent of cellular division undergone by responding T cells, but not by(More)
