Antigenic determinants on B cells of farmer's lung patients. 1982

S Koskimies, and E O Terho, and O P Heinonen, and R Mäntyjärvi

Peripheral B lymphocytes of 36 HLA typed farmer's lung (FL) patients were tested in a microcytotoxicity assay with 37 sera from multiparous women. The sera had been previously found negative with T lymphocytes from 150 healthy persons. The control groups consisted of 24 healthy spouses of the FL patients, 30 healthy local people, and 58 healthy kidney donors, each HLA typed. B cells from 75% of the FL patients, but only from 25 to 40% of the controls, reacted with six of the 37 sera. Mixed lymphocyte culture tests with lymphocytes of six positive FL patients and their seven HLA identical healthy siblings also revealed antigens on patients' B cells. The reactions are unlikely to be explainable by determinants of the known major histocompatibility antigens.

UI MeSH Term Description Entries
D007959 Lymphocyte Culture Test, Mixed Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

D008297 Male Males
D005203 Farmer's Lung A form of alveolitis or pneumonitis due to an acquired hypersensitivity to inhaled antigens associated with farm environment. Antigens in the farm dust are commonly from bacteria actinomycetes (SACCHAROPOLYSPORA and THERMOACTINOMYCES), fungi, and animal proteins in the soil, straw, crops, pelts, serum, and excreta.

D006680 HLA Antigens Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine tissue types for transplantation, and are associated with certain diseases.
