From AI:QuoteT lymphopenia is a condition where there's an abnormally low count of T-cells,, a crucial type of lymphocyte (white blood cell) that fights infections and abnormal cells, making the immune system weaker and increasing susceptibility to illness. It's a specific type of lymphopenia (low lymphocytes) and can stem from genetic issues, severe viral infections (like HIV, COVID-19), autoimmune diseases, malnutrition, or treatments like chemotherapy, leading to recurrent infections.\From Multiple Sclerosis Journal - Experimental, Translational and Clinical (January 2, 2026)--"T lymphopenia in MS patients treated with ofatumumab":https://journals.sagepub.com/doi/full/10.1177/20552173251409954 Last Edit: January 04, 2026, 09:20:32 pm by agate Logged MS Speaks--online for 20 yearsSPMS, diagnosed 1980.
