title: Syngeneic mixed lymphocyte reactions to murine Fc receptor-bearing, nonadherent low density lymph node cells and epidermal Langerhans cells.
abstract: Both Langerhans cells from BALB/c mouse epidermis and nonadherent, low density (LD) cells, obtained from collagenase-treated minced lymph node, are stimulatory for isolated T cells in syngeneic mixed lymphocyte reaction (SMLR). The method of preparation of LD cells influences whether Fc receptor (FcR) can be detected on them. Fc receptors on nonadherent LD lymph node cells can be detected only if the same procedure is employed as that for Langerhans cell isolation, i.e., Ig-free bovine albumin must be used during gradient centrifugation and EA rosetting must be done overnight at 4 degrees C. Thus, both FcR+ and FcR- LD lymph node cells, as well as FcR+ Langerhans cells, stimulate SMLR. Although Ig+ cells in the LD fraction also stimulate the SMLR, their removal does not affect the stimulating capacity of the LD lymph node fraction.
