The study looked at how levels of antibodies against a thymus‑derived peptide (thymogen) relate to different types of T‑cells in people with lung TB or cancer. In TB patients, higher thymogen antibodies were linked to lower counts of some T‑cells and higher counts of others, while cancer patients showed a different pattern. The authors suggest measuring these antibodies could help spot immune problems, especially in inflammatory diseases, but they don’t give any clear ways to use this info for health hacks.

A relationship of the levels of thymic peptide antibodies to those of the population and subpopulations of T lymphocytes was studied in patients with pulmonary tuberculosis, lung or breast cancer. Indirect immunofluorescence was used to determine the count of CD3-, CD4-, CD80, CD38-, CD25-, CD71-, and CD95-lymphocytes. The levels of thymic peptide antibodies were estimated by enzyme immunoassay. Unlike cancer diseases, pulmonary tuberculosis was characterized by the combination of a significantly inverse correlation between the relative count of CD3-, CD4-, CD8-lymphocytes the levels of thymogen antibodies with a significantly direct correlation between the absolute count of CD25- and CD38-lymphocytes. The studies may recommend that the levels of thymic peptide antigens should be determined to select persons with immunodeficiency particularly those with inflammatory diseases.
