Chemoimmunotherapy reduces the progression of multiple myeloma in a mouse model.

Multiple myeloma (MM) is a B-cell malignancy characterized by clonal proliferation of malignant plasma cells in the bone marrow. Recently, we showed a correlation between increased ratios of functional regulatory T cells (Treg) and disease progression in a unique mouse model that mimics the human disease. Cyclophosphamide (CYC) is a cytotoxic alkylating agent widely used in chemotherapeutic regimens.

Amelioration of brain pathology and behavioral dysfunction in mice with lupus following treatment with a tolerogenic peptide.

Objective: Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) is manifested by neurologic deficits and psychiatric disorders. The aim of this study was to examine SLE-associated CNS pathology in lupus-prone (NZBxNZW)F1 (NZB/NZW) mice, and to evaluate the ameliorating effects of treatment with a tolerogenic peptide, hCDR1 (human first complementarity-determining region), on these manifestations.

Methods: Histopathologic analyses of brains from lupus-prone NZB/NZW mice treated with vehicle, hCDR1, or a control scrambled peptide were performed.

A daidzein-daunomycin conjugate improves the therapeutic response in an animal model of ovarian carcinoma.

The use of daunomycin against neoplasms is limited due to its severe cardiotoxicity. The cytotoxicity of daunomycin can be minimized by linking it to an affinity tag. Since ovarian cancer cells are sensitive to isoflavone action, we synthesized a daidzein daunomycin conjugate.

Peptides based on the complementarity-determining regions of a pathogenic autoantibody mitigate lupus manifestations of (NZB x NZW)F1 mice via active suppression.

Two peptides based on the complementarity-determining regions (CDR) 1 and 3 (pCDR1 and pCDR3) of a murine monoclonal anti-DNA autoantibody that expresses the common idiotype 16/6Id were shown to down-regulate systemic lupus erythematosus (SLE)-associated T cell responses and to prevent the development of clinical symptoms in the SLE-prone mice, (NZB x NZW)F(1). In the present study the ability of the CDR-based peptides to treat an already established disease was tested. Mice were given 10 weekly injections of peptides either i.

Exogenous Dp71 is a dominant negative competitor of dystrophin in skeletal muscle.

Dystrophin, the protein which is absent or non-functional in Duchenne muscular dystrophy, consists of four main domains: an N-terminal actin binding domain, a rod shaped domain of spectrin-like repeats, a cysteine-rich domain and a unique C-terminal domain. In muscle, dystrophin forms a linkage between the cytoskeletal actin and a group of membrane proteins (dystrophin associated proteins). The N-terminal domain binds to the cytoskeletal actin and the association with the dystrophin associated proteins is mediated mainly by the cysteine-rich and C-terminal domains of dystrophin.
