Life span of lymphocytes The lifespan of lymphocytes can vary greatly due to their different tasks: lymphocytes that never came into contact with antigens (foreign body structures) die after only a few days, while activated lymphocytes, e.g. plasma cells, can survive for about 4 weeks. The longest survival is achieved by memory cells, which can … Life span of lymphocytes | Lymphocytes – You should definitely know this!
Lymphocyte Typing Lymphocyte typing, also called immune status or immunophenotyping, is a procedure that studies the formation of different surface proteins, mostly so-called CD markers (cluster of differentiation). Since these proteins differ in the different lymphocyte types, a so-called expression pattern of the surface proteins can be created by using artificially produced, color-marked antibodies. This … Lymphocyte Typing | Lymphocytes – You should definitely know this!
What are antibodies? Antibodies – also known as immunoglobulins or short: Ak or Ig – are important components of the body’s own defence system, which are formed by the B cells or plasma cells, a subclass of lymphocytes. This is a group of proteins formed by the human organism which serve to defend the body … Antibodies
Structure of the antibodies The structure of each antibody is usually the same and consists of four different amino acid chains (amino acids are the smallest building blocks of proteins), two of which are called heavy chains and two are called light chains. The two light and the two heavy chains are completely identical and … Structure of the antibodies | Antibodies
What are antigens? Antigens are structures or substances on the surface of cells in the human body. They are mostly proteins, but can also be fats, carbohydrates or even completely different compositions. Either they are the body’s own structures, which under normal circumstances are always present in the human body, or they are foreign structures … What are antigens? | Antibodies
Antibody treatmentbehandlung As described above, antibodies actually serve to protect against diseases, i.e. they are part of the immune system. However, some diseases, such as cancer, cannot be fought by our immune system alone, as it is not fast and effective enough for this. For some of these diseases, many years of research have led … Antibody treatmentbehandlung | Antibodies
Autoantibodies Autoantibodies are antibodies that the body forms in order to recognize and bind endogenous cells in tissues, hormones or other antibodies. By binding the autoantibodies to these structures, the immune system is activated and fights these structures. Autoantibodies are produced in the context of autoimmune diseases. Autoantibodies therefore do not help our immune system … Autoantibodies | Antibodies
Introduction In addition to the occurrence of physical symptoms, pneumonia usually also leads to a change in blood values. By taking blood samples from the affected persons, the blood can be examined in the laboratory for signs specific to inflammation, and in the case of positive infection values, this can support the diagnosis of pneumonia. … Blood values for pneumonia
Introduction Every person has about 4-6 litres of blood flowing through his veins. This corresponds to about 8% of the body weight. The blood consists of different proportions, which all take on different tasks in the body. For example, the components play an important role in the transport of nutrients and oxygen, but also for … Functions of the blood
Tasks of the white blood cells The white blood cells (leukocytes) serve the immune defence. They are important in the defence against pathogens and also in the development of allergies and autoimmune diseases. There are many subgroups of leukocytes. The first subgroup is the neutrophilic granulocytes with about 60%. They are able to recognize and … Tasks of the white blood cells | Functions of the blood
Tasks of the electrolytes Various electrolytes are dissolved in the blood. One of them is sodium. Sodium is much more concentrated in the extracellular space, which includes the blood plasma, than within the body cells. It is this difference in concentration that makes special signal transmissions in the cell possible. Sodium is also important for … Tasks of the electrolytes | Functions of the blood
Blood formation Hematopoiesis, also known as haematopoiesis, refers to the formation of blood cells from haematopoietic stem cells. This is necessary because the blood cells have a limited life span. Thus erythrocytes live for up to 120 days and thrombocytes for up to 10 days, after which renewal is necessary. The 1st place of blood … Blood formation | Functions of the blood
