BACKGROUND Malignant melanoma, the most serious cutaneous malignancy, has attracted substantial attention because of its rapidly increasing incidence and the poor prognosis of some tumours. Little is known of the genetic factors that mediate susceptibility to, and outcome of, sporadic malignant melanoma. Because of its role in mitogenesis, which is(More)
BACKGROUND/AIMS Alzheimer disease (AD) is a complex and genetically heterogeneous disorder, and certain genes such as PS2 and APOE4 contribute to the development of AD. Due to its heterogeneity, AD-predisposing genes could vary in different populations. Moreover, not all AD patients will respond to the same therapy. We specifically investigated the effect(More)
CD24 is a glycosylphosphatidylinositol (GPI)-linked cell surface glycoprotein expressed in central nervous system cells. Recent investigations have suggested that CD24 participates in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). However, a limited number of studies have been published(More)
The 32-base pair deletion on the C-C chemokine receptor 5 gene (CCR5-delta 32) is known as a protective allele against immune system disorders. We have studied this variation in Iranian multiple sclerosis (MS) patients and healthy controls. DNA samples were prepared from the whole blood of 254 patients with MS and 380 healthy controls. We amplified the(More)
Cerebral cavernous malformations (CCM) are congenital vascular anomalies predominantly of the central nervous system but may include lesions in other tissues such as the retina, skin, and liver. These hamartomatous dysplasias, generally occurring sporadically, consist of dynamic clustered convoluted capillary cavities without intervening brain parenchyma(More)
BACKGROUND Based on differences in individual immune responses to the hepatitis B virus (HBV), between 5% and 10% of patients become persistently infected with the virus, which leads to the determination of chronic HBV. Cytokines such as interferon gamma (IFN-γ) are secretory proteins that play important roles in both innate and adaptive immune responses.(More)
BACKGROUND Human insulin-like growth factor type 1 (hIGF-1) is a protein consisting of 70 amino acids (MW=7.6 kDa) and mainly synthesized by liver. Mecasermin (Trade name INCRELEX) is the synthetic form of the protein which is used as an effective treatment for particular disorders such as short stature, type 1 and 2 diabetes, and wound healing. Current(More)
Multiple sclerosis (MS) is a multi-factorial autoimmune disease of the central nervous system. The exact etiology of MS is still unknown. Due to the important roles that cytokines play as mediators in immune and inflammatory responses, we have evaluated the association of IL-1 gene cluster polymorphisms and haplotypes with MS susceptibility in 306 unrelated(More)
