Urokinase-type plasminogen activator (uPA)(-/-) mice cannot mount protective host defenses during infection with the opportunistic yeast Cryptococcus neoformans (52D). Because effective host defense against C. neoformans requires specific immune responses and the generation of type 1 (T1) cytokines, we determined how the absence of uPA impacts these processes. Wild-type (WT) and uPA(-/-) mice w...

Psoriasis is a long-lasting skin disease identified by excessive proliferation of epidermal keratinocytes. triggers an inflammatory reaction, which involuntary activates the immune system, leading to leukocyte infiltration into skin. However, supplementation diet with diverse supplements, including n-3 polyunsaturated fatty acids (n-3 PUFAs), namely alpha-linolenic acid (ALA), beneficial for ps...

The present study was designed to investigate the immunomodulatory activity of the ethanolic extract of Tinospora cordifolia (Family: Menispermaceae) stem (climbing shrub, mango plant) at cellular level. For antioxidant study, the liver mitochondria were separated and the concentration of enzymes like lipid peroxidation (LPO), reduced glutathione (GSH), catalase (CAT) and superoxide Dismutase (...

Recent scientific evidence indicates that distinct patterns of susceptibility in BALB/c mice to Leishmania major infection are attributable to the differential expansion of distinct CD4+ T-cell subsets and their cytokines production. Production of the Th1 cytokine IFN-g is associated with resistance, whereas production of the Th2 cytokines IL-4 and IL-10 are associated with extreme susceptibili...

BACKGROUND In clinical studies, the findings on sulfur mustard (SM) toxicity for CD3(+)CD4(+) and CD3(+)CD8(+) T lymphocyte subsets are contradictory. In animal experiments, the effect of SM on the T cell number and proliferation is incompatible and is even the opposite of the results in human studies. In this study, we observed the dynamic changes of T lymphocytes in the first week in a high-d...

Cucurbitacin R is known to exhibit an anti-inflammatory effect in different experimental models of inflammation. In this article, we outline the effect of cucurbitacin R on T lymphocyte proliferation, cytokine production, and nuclear factor activation, as well as its influence on various experimental models of delayed-type hypersensitivity (DTH) in mice. Cucurbitacin R reduced the proliferation...

Clam peptides, marine-derived biological have been broadly investigated and applied as health foods, among which immunomodulation is one of their activities that cannot be ignored in vivo. In this study, we concentrated on exploring the effects Ruditapes philippinarum peptides (RPPs) balance intestinal microbiota hydrocortisone (HC)-induced immunosuppressed mice. The results revealed RPPs could...

A lymphocyte blastogenesis inhibitory factor (LBIF) has been char acterized as an immunoregulatory molecule, especially on the T-lymphocyte proliferation. Using fast protein liquid chromatography-purified LBIF, we examined the effect of LBIF on the proliferation of various 18 tumor cell lines in vitro in comparison with those of interferon-a, interferon-7, tumor necrosis factor-a, transforming ...

Objective(s):Pentoxifylline is an immunomodulatory and anti-inflammatory agent and is used in vascular disorders. It has been shown that pentoxifylline inhibits proinflammatory [d1] cytokines production. The purpose of this study was to investigate the therapeutic effects of pentoxifylline on the treatment of autoimmune diabetes in mice. Materials and Methods: Diabetes was induced by multiple l...
