The key function of IRAK-4 in the inflammation signal pathway mediated by Toll-like receptors
LI Fan, RUI Yao-Cheng
2011, 29(1): 1-3,14.
Abstract(2910)
Abstract:
interleukin-1 receptor-associated kinase 4 (IRAK-4) is a key molecular which participates in the innate immune processes. It belongs to the IRAK family with the other three members: IRAK-1, IRAK-2, and IRAK-M. However, It has been found that IRAK-4 plays a more important role in the inflammatory signal pathway mediated by TLRs/IL-1Rs through the deep investigation of the IRAK-4 kinase activity and the positive/negative regulation mechanism of the inflammatory reactions. The activities of IRAK-4 and the crucial function of IRAK4 in the TLRs/IL-1Rs mediated pathways of inflammatory signal transmission were summarized.

Research progress of chitosan derivatives as gene delivery vector
LI Yan
2011, 29(1): 8-10,61.
Abstract(2348)
Abstract:
Despite the advantages of chitosan as a non-viral gene delivery vector, the application of this system is significantly limited by its poor solubility (the amino groups on chitosan are only partially protonated at physiological pH 7.4), poor stability of the polyplex at physiological pH, low cell specificity and therefore low transfection efficiency. Chitosan structure modification or additive incorporation is an effective way to improve the stability of the polyplex in biological fluids, enhance targeted cell delivery and facilitate endo-lysosomal release of the complex. In this paper, chitosan derivatives as gene delivery vector were reviewed to facilitate the process of chitosan vector development for clinical application.
