although both populations of cells appeared to be equally effective as antigen-presenting cells appropriately sensitized lymphocytes in the presence of specific antigens -- soluble schistosomal egg antigen ( sea ) and human gamma-globulin ( hgg ) -- only nu/nu gm , but not nu/+ gm , were found to stimulate i-a-restricted proliferation of schistosome-sensitized t cell populations in the absence of sea added in vitro .
