Immunostimulatory activity of lactotransferrin and maturation of CD4- CD8- murine thymocytes.

abstract：:The monocytic cell line I937 was derived from U937 by sorting for cells with high expression of MHC class II molecules. Further analysis of these class II molecules revealed the presence of the HLA-DR3 subtype suggesting that the cell line was a potential candidate for testing antigen presentation to T cells restricte...
