The action of 3-hydroxyanthranilic acid and other tryptophan metabolites on stimulated human lymphocytes. 1975

F A Teulings, and P H Lems, and H Portengen, and M S Henkelman, and D I Blonk

Short term cultures of phytohemagglutinin stimulated lymphocytes were used to study effects of tryptophan metabolites of the kynurenine pathway at the cellular level. Only the metabolites 3-hydroxyanthranilic acid and 3-hydroxykynurenine demonstrated an effect when (3H) thymidine was used to monitor the response. Morphological examination of the cultures did not clearly reveal an effect. Because the adenosine triphosphate level was also decreased upon the addition of 3-hydroxyanthranilic acid the possibility is considered that the mechanism of action of the metabolite on cultured lymphocytes can be explained by a suppression of the oxydative phosphorylation.

UI MeSH Term Description Entries
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

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
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D000255 Adenosine Triphosphate An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.

D013936 Thymidine A nucleoside in which THYMINE is linked to DEOXYRIBOSE. 2'-Deoxythymidine,Deoxythymidine,2' Deoxythymidine
D014364 Tryptophan An essential amino acid that is necessary for normal growth in infants and for NITROGEN balance in adults. It is a precursor of INDOLE ALKALOIDS in plants. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid). It can be a precursor to NIACIN, albeit inefficiently, in mammals.
