In-vivo nuclear deposits of IgG were demonstrated by direct immunofluorescence in epidermal cells of normal skin from 6 patients with serum antibodies to an RNase-sensitive extractable nuclear antigen (ENA). Addition of complement to the skin sections showed that C3 could bind to epidermal cells with IgG deposits. A skin biopsy from a patient with polymyositis and serum antibodies to ENA, but w...

Although hyperacute rejection has been clinically and pathologically fully described in recipients of other solid organ transplants, to our knowledge, there have been no previous fully documented cases in recipients of lung transplants. This case of clinical hyperacute rejection is corroborated by a positive, donor-antigen-specific IgG-mediated lymphocytotoxic crossmatch (LXM), and demonstrated...

Exposure of both mammalian and reptilian cells in tissue culture to different strains of fixed rabies virus resulted in a carrier type of infection. No cytopathic effect was observed in either type of culture; infected cultures could be maintained by cell transfer for unlimited numbers of passages. A consistent pattern of cyclically rising and falling levels of viral infection was observed by f...

The tropism of the human T-cell leukemia virus type 1 (HTLV-1) for the cells of monocyte-macrophage lineage was evaluated by the coculture of blood monocyte-derived macrophages, with irradiated cells of HTLV-1 producing cell lines MT2 or C91/PL. The susceptibility to HTLV-1 was assessed by the detection of viral DNA using the polymerase chain reaction method. HTLV-1 gene expression in the cells...

Anti-Malassezia furfur monospecific polyclonal antibodies was produced by repeated immunization of rabbit with Malassezia furfur yeast cells mixed with Freud adjuvant. The antibody titres of respective rabbit's serum samples prior to and after each immunization against M. furfur were assayed by indirect immunofluorescence technique using the M. furfur whole yeast antigen fixed in Teflon coated ...

Fifteen monoclonal antibodies (MAbs) raised against human sperm cells were evaluated for reactions against human sperm by indirect immunofluorescence, immunocytochemistry, agglutination, complement-dependent immobilization, cervical mucus penetration, and hamster egg penetration assays. The MAbs were analyzed for specificity by immunofluorescent reactions with peripheral blood lymphocytes and s...

In previous work we transferred a human factor IX-encoding adeno-associated viral vector (AAV) into skeletal muscle of men with severe hemophilia B. Biopsy of injected muscle up to 1 year after vector injection showed evidence of gene transfer by Southern blot and of protein expression by IHC and immunofluorescent staining. Although the procedure appeared safe, circulating F.IX levels remained ...
