The systemic lupus erythematosus-like syndrome in MRL/lpr mice involves high-titered IgG autoantibodies, particularly antinuclear Abs that target histones, DNA, and RNA particles. Although T cell help is required for the generation of antinuclear Abs, the epitopes recognized by such helper T cells are unknown. To address this question, we isolated and sequenced self peptides bound by MHC class ...
A RIAM/lamellipodin–talin–integrin complex forms the tip of sticky fingers that guide cell migration
The leading edge of migrating cells contains rapidly translocating activated integrins associated with growing actin filaments that form 'sticky fingers' to sense extracellular matrix and guide cell migration. Here we utilized indirect bimolecular fluorescence complementation to visualize a molecular complex containing a Mig-10/RIAM/lamellipodin (MRL) protein (Rap1-GTP-interacting adaptor molec...
Relative proportions of histone H1 proteins were determined for brain, heart, liver, and spleen for five strains of mice as a function of age. The strains examined were SJL/J and MRL/MPJ-lpr/pr which develop early resistance to tolerance and A/J, C57BL/6J and MRL/MPJ-+/+ which do not. Heart, brain, and liver of most of these strains displayed significant relative increases in histone H1(0) and ...
The existing optimal design of the fixed sampling interval S2-EWMA control chart to monitor the sample variance of a process is based on the average run length (ARL) criterion. Since the shape of the run length distribution changes with the magnitude of the shift in the variance, the median run length (MRL) gives a more meaningful explanation about the in-control and out-of-control performances...
MRL/l mice develop progressive, virulent autoimmune disease that has many of the features of systemic lupus erythematosus. Prophylactic treatment of MRL/l mice with syngeneic photoinactivated autoimmune splenocytes improves survival and inhibits the fulminant hyperproliferation of abnormal T cells and the production of high titer anti-DNA antibody invariably found in untreated mice. The prolife...
The death receptor, Fas, has been well-characterized and is a critical factor in apoptosis in immune cells. Fas also has an important role in maintaining immune tolerance as demonstrated in the autoimmune-prone MRL/lpr mouse strain which carries a defect in Fas-mediated apoptosis of T cells. However, the role of Fas-independent apoptosis remains to be characterized in autoimmune diseases. In de...
OBJECTIVE Similar to patients with systemic lupus erythematosus, autoimmune MRL/lpr mice spontaneously develop behavioral deficits and pathologic changes in the brain. Given that the disease-associated brain atrophy in this model is not well understood, the present study was undertaken to determine the time course of morphometric changes in major brain structures of autoimmune MRL/lpr mice. M...
BACKGROUND Hearing evaluation in children. AIM To verify the Minimum Response Levels (MRL) through the use of Visual Reinforcement Audiometry (VRA) in the sound field, in 50 normal hearing children and in 25 children with hearing loss, taking into account the following variables: side of sound presentation, gender, age and type of stimulus. METHOD VRA was performed using pure tone frequency...
OBJECTIVE To clarify the role of T cells in kidney pathology of three widely used murine lupus models. MATERIAL AND METHODS Cells infiltrating the glomeruli and perivascular areas in MRL/lpr (n = 10 female), NZB× NZW F1 (B/W F1) (n = 9 female), and BXSB (n = 10 male) mice were captured by laser microdissection (LMD). Samples were subjected to nested reverse transcription polymerase chain reac...
Intractable autoimmune diseases in chimeric resistant MRL/lpr mice were treated by a new bone marrow transplantation (BMT) method consisting of fractionated irradiation, 5.5 Gy x 2, followed by intra-bone marrow (IBM) injection of whole bone marrow cells (BMCs) from allogeneic normal C57BL/6 (B6) mice (5.5 Gy x 2 + IBM). In MRL/lpr mice treated with this method, the number of donor-derived cell...
