Black/New Zealand White Lupus-Prone Suppression of Disease in New Zealand

Black/New Zealand White Mice Autoreactivity in Lupus-Prone New Zealand L Chain Allelic Inclusion Does Not Increase

Reversal of autoimmune disease in lupus-prone New Zealand black/New Zealand white mice by nonmyeloablative transplantation of purified allogeneic hematopoietic stem cells.

Patients with severe systemic lupus erythematosus (SLE) refractory to conventional treatment are candidates for autologous hematopoietic stem cell (HSC) transplantation if the intent is to reset the immunologic clock. These patients might be candidates for allotransplantation with (SLE)-resistant major histocompatibility complex (MHC) haplotype-matched HSC if partial or complete replacement of ...

A novel locus regulates both retroviral glycoprotein 70 and anti-glycoprotein 70 antibody production in New Zealand mice when crossed with BALB/c.

Lupus-prone New Zealand Black and New Zealand White mice produce high serum levels of the endogenous retroviral envelope protein gp70 and develop an Ab response to this autoantigen as part of their autoimmune disease. Linkage analysis of two crosses involving New Zealand and BALB/c mice mapped these traits to a group of overlapping loci, including a novel locus on proximal chromosome 12. This l...

L chain allelic inclusion does not increase autoreactivity in lupus-prone New Zealand Black/New Zealand White mice.

L chain allelic inclusion has been proposed as a B cell tolerance mechanism in addition to clonal deletion, clonal anergy, and receptor editing. It is said to rescue autoreactive B cells from elimination by diluting out the self-reactive BCR through the expression of a second innocuous L chain. In autoimmune animals, such as lupus-prone mice, allelically included B cells could be activated and ...

New loci from New Zealand Black and New Zealand White mice on chromosomes 4 and 12 contribute to lupus-like disease in the context of BALB/c.

New Zealand Black (NZB) and New Zealand White (NZW) mice are genetically predisposed to a lupus-like autoimmune syndrome. To further define the loci linked to disease traits in NZB and NZW mice in the context of the BALB/c genetic background, linkage analyses were conducted in two crosses: (NZW x BALB/c.H2(z))F(1) x NZB and (NZB x BALB/c)F(2). Novel loci linked to autoantibody production and gl...
