E rosette‐forming lymphocytes in multiple sclerosis patients. Basic protein stimulation of rosette‐forming cells

“Total” and “active” T cells were enumerated using sheep red blood cell (SRBC) rosetting technique. the percentages of “total” and “active” T lymphocytes were not significantly different in multiple sclerosis patients as compared to other neurological disorders and/or healthy controls. However, the number of “avid” T cells binding more than three SRBC was significantly increased in MS patients. Active E rosette test has shown hypersensitization to myelin basic protein in 50 % MS patients and 31 % OND patients. All healthy controls studied, except one had negative response.
