The in vitro secondary cytotoxic T lymphocyte (CTL) response to Sendai virus-treated stimulator cells by primed spleen cells from thymus gland-grafted nude mice was examined. BALB/c (H-2d) nude mice grafted with allogeneic C57BL/10 (H-2b) thymus glands developed CTL responses directed exclusively to Sendai virus-infected H-2d target cells. (C57BL/6 X BALB/c)F1 nude mice grafted with thymus glan...

Thymus herba-barona, Thymus pseudolanuginosus, and Thymus caespititius decoctions were screened for their phenolic constituents, along with their potential antioxidant, anti-inflammatory, and antibacterial activities. The total phenolic compounds in the extracts of the three plants ranged from 236.0 ± 26.6 mgGAE/g (T. caespititus) to 293.0 ± 30.5 mgGAE/g of extract (T. pseudolanuginosus), being...

Research data presented in the article are based, mainly, on concept that thymus, together with bone marrow represent central organ of immune system being source all T cell populations that, following their migration from thymus to periphery, participate development response any antigens viral, bacterial and tissue origin, allergens. This difference is principal, as opposed which produces other...

Thymus-derived lymphocytes (T cells) have two outstanding characteristics that distinguish them from other lymphocytes: (a) they express two specificities, one for self-antigens, the major transplantation antigens (H) coded by the major histocompatibility gene complex (MHC), and a second specificity for foreign antigenic determinants. (b) T cells must undergo differentiation or maturation in th...

Cytochrome P450 (P450) monooxygenases play a role in target tissue metabolic activation of xenobiotics and/or endogenous compounds, such as vasoactive molecules or hormones. Indeed, tissue-specific metabolism of steroids is important in a variety of organs, including thymus, and may alter tissue-specific functions. Steroids have been shown to regulate thymus growth and function, but surprisingl...

for developmental study of thymus in different stages offetal period, from thymus glands of75 healthy fetuses. histological sections were prepared and stained by h&e;, pas, verhoeff, toluidine blue and van geisson's methods. this study revealed that, the infiltration and accumulation of lymphocytes in thymus takes place at second month. medullae were expanded and cortices were seen as accu...

The effects of crude thymus extract on the immune response and protection against challenge with virulent infectious bursal disease virus (IBDV) were studied in one-day-old chick. Oral administration of thymus extract (1 ml/kg) markedly and significantly increased the total protein, albumin, globulin, Tri-iodothyronine (T3), Thyroxine (T4) and the body weight gain in one-day-old chick. In addit...
