2. T-Cell Disorders

T-cell disorders are conditions that affect T-cells, which are a type of white blood cell crucial for the immune system. T-cells help the body fight infections and diseases, including cancer. When T-cells are dysfunctional, it can lead to autoimmune diseases (where the body attacks itself), immunodeficiencies (where the body struggles to fight infections), or certain types of cancer, such as lymphomas. These disorders can result from genetic factors, infections, or environmental influences, and they can impact the body's ability to respond to pathogens or regulate its immune response properly.
