Researchers Report that Thymosin B4 has a Major Role in Dermal Burn Wound Healing
PR Newswire

ROCKVILLE, Md., May 4, 2015 /PRNewswire/ -- RegeneRx Biopharmaceuticals, Inc. (OTCQB: RGRX) ("the Company" or "RegeneRx") today announced that an independent team of researchers from South Korea have reported that Thymosin B4 (TB4) plays an important role in accelerating the repair of second-degree dermal burn wounds, induced in an experimental mouse model, by promoting blood vessel formation and causing rapid vascular remodeling of damaged dermal tissue.  The research found that the underlying mechanism of action is via actin cytoskeletal remodeling and the action of heat-shock proteins, which are induced when tissues or cells are exposed to stress.  Heat shock proteins function to allow other proteins to assume their correct structures. The research also confirmed that remodeling of F-actin was regulated by TB4 by demonstrating its healing effects in the in vivo model.

"These results show an additional new potential application for TB4 and provide a greater understanding of its effects in dermal wound healing and specifically in the healing of dermal burns.  Since the skin is the primary immune organ, understanding impaired immune function resulting from severe dermal burns, and the ability to successfully treat the affected area, is important knowledge necessary to adequately address this unfortunate injury, which can cause prolonged hospitalization, increase the risk of amputation, and lead to death due to infection and organ failure," stated Dr. Allan L. Goldstein, Emeritus Professor and Former Chairman of the Department of Biochemistry and Molecular Medicine at The George Washington University School of Medicine in Washington, DC.  Dr. Goldstein is also RegeneRx's chairman and chief scientific advisor.

The research was conducted by Sokho Kim and Jungkee Kwon, Department of Laboratory Animal Medicine, College of Veterinary Medicine Chonbuk National University, Republic of Korea.  It was supported by the National Research Foundation of Korea, funded by the Korean government, and published in the Journal of Tissue Engineering and Regenerative Medicine, 2015 Apr 28. doi:10.1002/term.2028.
