Humoral immunity
Immunity against pathogens in the body fluids. Produced by the actions of lymphocytes, a type of white blood cell. B lymphocytes, or B cells, are responsible for producing antibodies
Humoral immunity is a type of immune response that is mediated by antibodies or immunoglobulins produced by plasma cells. These antibodies are produced by B-cells in response to foreign antigens, which are substances that can be recognized by the immune system as potentially harmful to the host.
Humoral immunity can be classified into two categories: primary and secondary responses. The primary response occurs when an individual is exposed to a new antigen for the first time and B-cells produce specific antibodies to combat the antigen. The secondary response occurs when an individual is exposed to the same antigen again and the immune system produces a faster and stronger response due to memory B-cells that recognize the antigen and produce antibodies more quickly.
Humoral immunity plays a crucial role in protecting the body against bacterial infections, viruses, and other foreign particles. This type of immunity can also be induced through vaccinations, which involve the introduction of weakened or inactive forms of the pathogen to stimulate the production of protective antibodies that can recognize the full-strength pathogen later on.
Overall, understanding humoral immunity is important in the development of immunotherapy and vaccination strategies to help fight against various diseases.
