Random Education: B Cells

About this video

In this Random Education installment, a rheumatologist tries to teach B cells with help from Ortho, who translates immunology into bone and college-football analogies. Flanary explains B cells as mediators of the humoral response that develop in marrow, mature in lymphoid tissues, and, on encountering antigen, become antibody-producing plasma cells and memory cells. Ortho’s surgeons-and-rivals metaphors make the basic immunology accessible while keeping the specialty comedy front and center.

Key takeaways

• Flanary presents B cells as mediating the humoral immune response
• The sketch describes B cells originating from marrow stem cells and gathering in lymph nodes, spleen, and other lymphoid tissue
• On antigen exposure, the sketch has B cells differentiate into plasma cells and memory cells
