Inherited deficiency of the seventh component of complement associated with meningococcal meningitis: lack of serum bactericidal activity against Neisseria meningitidis in a girl with C7 deficiency and HLA studies of a C7-deficient Japanese family.

abstract：:A human T-lymphoblastoid cell line, TCL-Fuj, produces large amounts of interferon (IFN)-gamma constitutively. A variant cell line, 2M, was derived from it. Both cell lines express similar surface antigen markers, but differ in surface morphology. Compared with the parent TCL-Fuj cell line, 2M produced less IFN-gamma c...
