Expression of major histocompatibility complex antigens on the bovine placenta.

Immunohistochemistry was utilized to determine expression of the major histocompatibility complex (MHC) antigens on Day 8-9 hatched blastocysts and fetal membranes of mid- to late gestation cows and to examine the pattern of leucocytic infiltration into the gravid uterus. Hatched blastocysts were weakly positive for MHC class I antigens. In the mature placenta, chorioallantoic membranes in the ...

Major histocompatibility antigen expression on the bovine placenta: its relationship to abnormal pregnancies and retained placenta.

In viviparous animals, regulation of expression of major histocompatibility complex (MHC) class I antigens by the trophoblast cells, which constitute the outermost layer of the placenta, seems to be critical for maternal immunological acceptance of an allogeneic fetus. Cattle are unusual in this regard, since the bovine trophoblast cells, in specific regions of the uterine/placental interface, ...

Modulation of the Expression of Major Histocompatibility Antigens on Splenic

The mechanism of action responsible for the beneficial effect of alpha-interferon (a-IFN) in patients with hairy cell leukemia (HCL) is still unknown. Direct antineoplastic and immunomodulating effects on both the host immune system and the hairy cells themselves have been implicated. To evaluate whether lymphokines have any regulatory effect on antigens of the major histocompatibility complex ...

Frequency of Major Histocompatibility Antigens Class I in Mazandaran Province

 Background and purpose: Major histocompatibility antigens are the most polymorphic components of the immune system. The purpose of this study was to determine the frequency of human leukocyte antigens (HLA) in a population in Mazandaran province, Iran. Materials and methods: In a cross sectional study, peripheral blood samples were obtained from 550 people in Immunogenetics Research Center af...

Expression of major histocompatibility antigens on pancreatic islet cells.

Insulin-dependent diabetes mellitus is often accompanied by manifestations of autoimmunity and is frequently associated with certain HLA haplotypes, predominantly DR3 and DR4. Because the major histocompatibility antigens are important determinants of the immune response in various tissues, we have investigated their expression on the pancreatic islet cells. Human, mouse, or rat islets of Lange...
