Study Notes
Autoimmune Diseases
- Autoimmune diseases, such as lupus erythematosus, stem from abnormal antibody production targeting normal tissues in the body.
- The immune system mistakenly identifies parts of the body as foreign, leading to inflammation and damage.
Immunoglobulin Production
- B cells are the primary cells responsible for producing immunoglobulins (antibodies) that help in identifying and neutralizing pathogens.
ELISA Test
- The Enzyme-Linked Immunosorbent Assay (ELISA) test is utilized to detect specific antigens or antibodies in blood.
- It is frequently employed as a screening tool for conditions such as AIDS, helping to diagnose the presence of HIV antibodies.
Multiple Myeloma
- Multiple myeloma is not a benign tumor; it is a malignant condition characterized by the proliferation of abnormal plasma cells in the bone marrow, leading to various health issues.
