Abstract Stroke remains the leading cause of death and disability worldwide, which destroys the quality of patients’ lives and thus is becoming a heavy burden to the society. However, the current therapeutic approaches are far from satisfaction. The objective of this study is to elucidate the impact of nerve growth factor (NGF) on the brain damage induced by cerebral ischemia and its potential molecular mechanism. Middle cerebral artery occlusion (MCAO) rats were used as animal models and neurological functions were evaluated by modified Neurological Severity Score (NSS). Brain cell apoptosis was analyzed by TUNEL-positive staining while brain infarct size was determined… More >

Abstract Interleukin-22 (IL-22) is a member of IL-10 cytokine family which is expressed in activated T cells predominantly and in activated natural killer cells at lower levels. Previous studies have demonstrated the link between elevated levels of IL-22 and disease severity of psoriasis, Crohn’s disease, rheumatoid arthritis and interstitial lung diseases. However, the function of IL-22 in the development and progression of colorectal cancer (CRC) remains elusive. In this study, we first evaluated the IL-22/IL-22R1 level in CRC patients, and found that tumor tissues have more active expression of IL-22 and IL-22R1 than normal tissues, presenting correlation with the degree of… More >
