To assess the effects of transforming growth factor alpha (TGF-alpha) on mammalian skin in vivo, we have targeted its expression to the epidermis of transgenic mice using a vector based on the human K1 (HK1) gene. Neonatal mice expressing the HK1.TGF-alpha transgene were often smaller than normal littermates and had precocious eyelid opening and wrinkled,(More)

Elevated expression of matrix metalloproteinase-3 (MMP-3/stromelysin-1) is associated with a variety of tumor types, although its in vivo functional role remains unclear. In human and murine squamous cell carcinoma (SCC), MMP-3 is expressed in the stromal compartment at all of the stages of tumor progression and is expressed by the malignant epithelial(More)
Alzheimer's disease (AD) is characterized neuropathologically by the presence of neuritic plaques (NP) in cerebral cortex and hippocampus, as well as intraneuronal neurofibrillary tangles and granulovacuolar degeneration. The etiology of plaque formation has remained obscure, but morphologically NP are known to contain amyloid cores surrounded by astrocytes(More)
Recent data suggest that epidermal growth factor and epidermal growth factor receptors (EGF/EGF-R) are present and functional in neurons within the central nervous system. Previously, EGF was detected in developing and mature rat brain and cerebrospinal fluid. Also, EGF-R was documented in discrete locations in normal adult human brain, as well as in senile(More)
Alopecia areata (AA) is an autoimmune disease that attacks anagen hair follicles. Gene array in graft-induced C3H/HeJ mice revealed that genes involved in retinoic acid (RA) synthesis were increased, whereas RA degradation genes were decreased in AA compared with sham controls. This was confirmed by immunohistochemistry in biopsies from patients with AA and(More)
CD4(+)CD25(hi) FOXP3(+) regulatory T cells (Tregs) maintain tolerance to self-Ags. Their defective function is involved in the pathogenesis of multiple sclerosis (MS), an inflammatory demyelinating disease of the CNS. However, the mechanisms of such defective function are poorly understood. Recently, we reported that stimulation of TLR2, which is(More)
To the Editor Alopecia areata (AA) is a disfiguring human autoimmune skin disease with a complex genetic basis that targets hair follicles in the actively growing anagen phase of the hair cycle. AA is characterized by focal hair loss that waxes and wanes. Bald spots can become extensive involving the entire scalp (alopecia totalis) or body (alopecia(More)
