An immunomodulatory peptide derived from the thymus gland, approved in several countries for hepatitis B/C and studied for immune enhancement in cancer and infectious diseases.
Partially purified thymosin fraction 5 and one of its synthetic peptide components, thymosin beta 4, but not thymosin alpha 1, stimulated secretion of luteinizing hormone--releasing factor from superfused medial basal hypothalami from random cycling…
A mRNA fraction purified by preparative polyacrylamide disc gel electrophoresis from calf thymus polysomes codes for a polypeptide(s) having a mass of 16,000-17,000 daltons. This polypeptide contains amino acid sequences corresponding to residues 11-…
Thymosin alpha 1 (alpha 1) is a potent thymic polypeptide hormone. With antibodies against synthetic thymosin alpha 1, indirect immunofluorescence was applied to human normal thymus and to hyperplastic, thymomatous or "involuted" thymus of myasthenia…
Thymosin-alpha 1 (alpha 1) is a potent thymic polypeptide hormone. Using anti-alpha 1 antibodies, we applied indirect immunofluorescence to human normal thymus of different ages and to hyperplastic, thymomatous, and "involuted" thymus of myasthenia g…
Thymosin alpha 1, an immune restorative polypeptide hormone, was synthesized in Escherichia coli by using recombinant DNA cloning techniques. Based on the known amino acid sequence, a gene coding for the thymosin alpha 1 polypeptide chain was designe…
Thymosin alpha 1 and its desacetyl analogue were synthesized by the solid-phase method. Use of aminoacyl-4-(oxymethyl)phenylacetamidomethyl-resin resulted in an improved yield and allowed the synthetic products to be purified by simple ion-exchange a…
Thymosin fraction 5 contains several distinct hormonal-like factors which are effective in partially or fully inducing and maintaining immune function. Several of the peptide components of fraction 5 have been purified, sequenced and studied in assay…
The objective of the present study was to determine whether or not thymosin and conditioned medium from human thymus epithelial cultures (HTECM) contain similar fractions, capable of inducing T-cell differentiation. Therefore we tested the ability of…
