background: the aim of this study was to determine the th1 and th2 serum cytokines, in patients with psoriasis and to com pare their cytokine levels with those of normal control subjects. methods: serum levels of interferon-gamma (ifn-γ), interleukin-2 (il-2), interleukin-4 (il-4), and interleukin-10 (il-10) were measured by enzyme linked immunosorbent assay in 40 patients with psoriasis and in...

Background: Schizophrenia is a disorder of the executive function of both sensory and central nervous system. Recent studies suggest that immune mechanisms play a role in the pathophysiology of this disease.

The human body defends itself against foreign invaders such as bacteria and viruses by a defense system that involves antibodies and thymus-derived lymphocytes (T cells). A major advance over the past decade has been the demonstration that the diverse cells within the immunological network communicate with each other not only by cell/cell contact but also by an array of hormone-like proteins te...

conclusions increased serum levels of interleukins 6 and 8 as a predictive marker might be associated with unfavorable clinical outcome in patients with severe tbi. results comparing the serum levels of interleukins in two groups with favorable and unfavorable clinical outcomes showed that the mean serum levels of interleukins 6 and 8 in group with favorable outcome was 85.2 ± 51.6 and 52.2 ± 3...

Neuroblastoma is one of the most common solid tumors in childhood, with some unusual neoplastic behavior depending on the age of the affected children.
