In cases of immune-mediated arthritis in joints, what cell type is typically observed?

In cases of immune-mediated arthritis, lymphocytes are the predominant cell type involved in the inflammatory process. These immune cells play a critical role in the body's immune response by contributing to the activation and regulation of inflammation. In immune-mediated conditions, the presence of lymphocytes indicates an adaptive immune response, which is often characterized by the accumulation of these cells in affected tissues, such as the synovium of joints.

While neutrophils can be present in acute inflammation or infections, their presence is typically more associated with an inflammatory response to pathogens rather than a chronic immune-mediated condition. Eosinophils and basophils, on the other hand, are more commonly involved in allergic responses and parasitic infections rather than in arthritis. Therefore, the observation of lymphocytes in cases of immune-mediated arthritis reflects the long-term immune activity and the chronic nature of the condition.
