The diversity of autoimmune responses poses a formidable challenge to the development of antigen-specific tolerizing therapy. We developed myelin proteome microarrays to profile the evolution of autoantibody responses in experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis (MS). Increased diversity of autoantibody respo...
Melanoma claims approximately 9,000 lives in the United States annually. Patients who present with satellite, in-transit, or distant cutaneous metastases have limited treatment options and the prognosis for patients with metastatic disease remains poor. Surgical excision remains the most common treatment modality for cutaneous metastases, but may n...
A 13-year old girl was admitted to the University of California Davis Medical Center for evaluation and treatment of cutaneous bullae and ulcerations over her lower extremities that were refractory to antibiotic therapy and incision and drainage. Her disease continued to worsen with the appearance of multiple new bullae and the progression of old o...
Novel therapies for chronic graft-versus-host disease (cGVHD) are needed. Aberrant B-cell activation has been demonstrated in mice and humans with cGVHD. Having previously found that human cGVHD B cells are activated and primed for survival, we sought to further evaluate the role of the spleen tyrosine kinase (Syk) in cGVHD in multiple murine model...
ADAM12, adisintegrin and metalloprotease, has been demonstrated to be upregulated in human malignant tumors and to accelerate the malignant phenotype in a mouse model for breast cancer. ADAM12 is a substrate for beta1 integrins and may affect tumor and stromal cell behavior through its binding to beta1 integrins. Here, we report that cells deficien...
A 13-year-old girl presented with a history of red scaly plaques involving the chest, arms and legs beginning in infancy. Punch biopsy revealed psoriasiform hyperplasia and pallor of the epidermis. The patient s serum zinc level was 36 mug/dl [nl. 66-144 mug/dl]. A diagnosis of acrodermatitis enteropathica was established and the patient responded ...
Graft-versus-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation. It has been previously reported that lung GVHD severity directly correlates with the expansion of donor Th17 cells in the absence of IFN-γ. However, the consequence of Th17-associated lung GVHD in the presence of IFN-γ has not been well characterized...
Endogenous electric fields (EFs) occur naturally in vivo and play a critical role during tissue/organ development and regeneration, including that of the central nervous system(1,2). These endogenous EFs are generated by cellular regulation of ionic transport combined with the electrical resistance of cells and tissues. It has been reported that ap...
Integrin αvβ3 plays a role in insulin-like growth factor-1 (IGF1) signaling (integrin-IGF1 receptor (IGF1R) cross-talk). The specifics of the cross-talk are, however, unclear. In a current model, "ligand occupancy" of αvβ3 (i.e. the binding of extracellular matrix proteins) enhances signaling induced by IGF1 binding to IGF1R. We recently reported t...
