چکیده

Normal mouse sera contain naturally occurring antibodies that are cytotoxic in the presence of rabbit complement for NB1, a cell line derived from a neuroblastoma adrenal metastasis of a spontaneous ovarian teratoma. The anti-NB1 antibodies can be specifically removed from normal mouse sera by absorption of the sera with homogenized brain tissue of mouse, rat, guinea pig, chicken, and man and by homogenized kidney tissue of mouse and man. The antigen recognized by anti-NB1 naturally occurring autoantibodies, designated mouse brain antigen-2 (MBA-2), is not present on other normal tissues or tumor cell lines tested. MBA-2 is distinct from previously described mouse brain antigens.

Expression by human neuroblastoma cells of an antigen recognized by naturally occurring mouse anti-brain autoantibody.

A number of human tumor cell lines of both neural and nonneural origin have been assayed for the expression of an interspecies brain antigen (mouse brain antigen 2), detected by naturally occurring antibodies in normal mouse sera. These experiments indicate that mouse brain antigen 2 is present on four human neuroblastoma cell lines but not on other human tumor cell lines tested, including four...

Natural thymocytotoxic autoantibody and reactive antigen in New Zealand black and other mice.

Naturally occurring thymocytotoxic autoantibody (NTA) was detected by cytotoxic test in the sera of very young New Zealand Black mice (within 1 month after birth); the incidence was 100% at 3 months of age. Some mice from other strains also had NTA, but at an older age and with lower incidence and antibody titer. NTA had optimal activity at 4 degrees C but was also strongly reactive at 37 degre...

Antibodies to a Brain-Type Creatine Kinase: Biomarker of Cancer-Related Paraneoplastic Neurological Syndromes

The primary pathological mechanism for paraneoplastic neurological syndromes is believed to be a form of onconeural immunity where the cancer causes a cross-immune reaction with the neurons. In a previous study, using a proteomic approach, we detected an anti-brain-type creatine kinase antibody that was associated with paraneoplastic cerebellar degeneration. Using immunohistochemistry, we showe...

Effects of co-administration of ghrelin agonist (GHRP-2) and GH on TNF-α, IL-6 and iNOS gene expression induced by LPS in the mouse brain

The aim of this study was to examine the anti-inflammatory effects of co-administration of growthhormone-releasing peptide-2 (GHRP-2) and growth hormone (GH) on tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and inducible nitric oxide synthase (iNOS) gene expression induced by LPS in the mousebrain. Thirty-five male NMRI mice (25±5 g) were injected through the mouse tail vein with saline,...

AUTOANTIBODIES AGAINST THYR OID CONSTITUENTS AND CIC IN GRAVES\' DISEASE ASSOCIATED WITH EXOPH THALMUS

32 patients (19 female. 13 male)• suffering from Graves' disease with exophthalmus and five without exophthalmus were studied for various autoantibodies including anti-thyroglobulin (ATAB). anti-microsomal antibody (AMAB). anti-parietal antibodies (APAB) and also circulating immune complex (CrC). 43 normal subjects were tested concurrently. Immunofluorescent technique was employed for auto...
