Hla antibodies (HLA antibodies) are specific antibodies that are directed against certain HLA antigens (Human Leukocyte Antigen). These antigens are molecules that are found on the surface of blood cells and play an important role in the human immune system. They help recognize foreign cells and destroy them.
Hla antibodies can be found in the blood of patients with various diseases, such as autoimmune diseases, cancer, infectious diseases and others. They can also be used in the diagnosis of various diseases such as Crohn's disease, rheumatoid arthritis and others.
One of the most common types of HLA antibodies are IgG antibodies directed against the HLA-A, HLA-B and HLA-C antigens. These antibodies can be found in patients with various autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus and others.
For the last two decades, it has been customary to talk about human population genetics - a branch of evolutionary genetics, the subject of study of which is one of the main distinguishing features of the species Homo sapiens - its population genetics: a set of alleles, the frequency of occurrence of alleles and genotypes (groups of alleles) in the human population. In other words, population genetics studies the genetic composition of populations.
The most striking and poorly studied are the genetic markers of the HLA class. These markers represent groups of phenotypes that include a variety of
