The immune system responds to an infection by producing antibodies that recognize and bind to the cell surface of the ...

The following is a summary of "Impact of HBsAg reduction via siRNA treatment on natural and vaccine (BRII-179)-induced ...

Assays for hepatitis B surface antigen (HBsAg) are the most frequently used tests to detect HBV infection. Vaccination for HBV can produce transiently detectable levels of HBsAg in patients.

Medically reviewed by Amelia MacIntyre, DO One of the most important characteristics of blood is its type. Knowing your blood ...

Antigens live on the surface of your red blood cells. Antibodies are in your plasma. Your blood type is based on the combination of antigens and antibodies in your blood. Whether you are donating ...

The surface of our red blood cells have proteins, called antigens, which define our blood type. Type A blood contains Type A antigens and type B blood contains Type B antigens. There are 35 blood ...

Methods: We determined antibody to hepatitis B surface antigen (anti-HBs) at 4-13 years of age in 363 low risk children who had been vaccinated starting at birth with hepatitis B vaccine.

Antigenic variation is a key mechanism by which pathogens evade the immune system. New research has shown how trypanosomes change their antigen expression.

Antigen-presenting cells work to present peptides derived from exogenous and endogenous antigens to circulating T cells, sparking off an immune response. Dendritic cells are unique amongst antigen ...
