[Characteristics of immune response regulation in viral hepatitis A and B]
Abstract:
In 272 patients with virus hepatitis A and B the content of theophylline-sensitive lymphocytes (T-suppressors) and theophylline-resistant lymphocytes (T-helpers) in the peripheral blood was determined. Differences in the content of T-suppressors in cases of acute virus hepatitis A and B with an equal degree of severity were revealed: at the peak of hepatitis A infection in the mild form of the disease the number of the cells was decreased, while at the peak of hepatitis B infection an increase in their number was observed in the mild and moderate forms of the disease and a decrease, in the severe form of the disease. In chronic persistent hepatitis a decrease in the content of T-suppressors and an increase in the content of T-helpers were observed, and in chronic active hepatitis (at the period of remission) and increase in the T-helpers occurred. Changes in the content of the cells of both types are not characteristic of HBsAg carriership.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
