[Effect of thymosin alpha 1 on prostaglandin release by murine lymphocytes]. 1985

A M Baldassarre, and G Stirparo, and A T Palamara, and A Padovani, and A Mastino

The effects on PGE2 release by lymphocytes obtained from adult thymectomized mice and from normal mice, after incubation with Thymosin alpha 1, were studied. Splenocytes from Tx mice release PGE2 at short time of incubation (15') using 4 micrograms/ml of Thymosin alpha 1 and at longer time of incubation (60'-180' using 4-8 micrograms/ml of Thymosin alpha 1. On the other hand thymocytes release the highest amounts of PGE2 after longer time of incubation (60'-180'). However lymphocytes obtained from normal mice do not release PGE2 amounts comparable with that released by the control samples. This effect shows an interesting interaction between thymic hormones and PGs.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297 Male Males
D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D011458 Prostaglandins E (11 alpha,13E,15S)-11,15-Dihydroxy-9-oxoprost-13-en-1-oic acid (PGE(1)); (5Z,11 alpha,13E,15S)-11,15-dihydroxy-9-oxoprosta-5,13-dien-1-oic acid (PGE(2)); and (5Z,11 alpha,13E,15S,17Z)-11,15-dihydroxy-9-oxoprosta-5,13,17-trien-1-oic acid (PGE(3)). Three of the six naturally occurring prostaglandins. They are considered primary in that no one is derived from another in living organisms. Originally isolated from sheep seminal fluid and vesicles, they are found in many organs and tissues and play a major role in mediating various physiological activities. PGE
D000077596 Thymalfasin A thymus hormone polypeptide found in thymosin fraction 5 (a crude thymus gland extract) but now produced by synthesis. It is used alone or with interferon as an immunomodulator for the treatment of CHRONIC HEPATITIS B and HEPATITIS C. Thymalfasin is also used for the treatment of chemotherapy-induced immunosuppression, and to enhance the efficacy of influenza and hepatitis B vaccines in immunocompromised patients.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013934 Thymectomy Surgical removal of the thymus gland. (Dorland, 28th ed) Thymectomies
D013947 Thymosin Thymosin. A family of heat-stable, polypeptide hormones secreted by the thymus gland. Their biological activities include lymphocytopoiesis, restoration of immunological competence and enhancement of expression of T-cell characteristics and function. They have therapeutic potential in patients having primary or secondary immunodeficiency diseases, cancer or diseases related to aging. Thymosin Fs,Thymosins
