- Lymphocytes are found in low numbers in breast milk. Colostrum
- is particularly lymphocyte-rich, containing up to 10e6/ml.
- They are not known to perform any useful function when
- transferred to the infant, however. There is only partial
- MHC compatibility between mother and infant, and that might
- reduce the effectiveness of baby's antigen-presenting cells
- at presenting antigen to mom's lymphocytes.
