• RegeneRx Biopharmaceuticals Inc., of Rockville, Md., reported preclinical data showing thymosin beta 4 (TB4) provided both neuroprotection and neurorestoration after traumatic brain injury. A study comparing TB4 with saline administration six hours post-injury in rats significantly improved sensorimotor functional recovery and spatial learning, reduced cortical lesion volume and hippocampal cell loss, and enhanced cell proliferation and neurogenesis in the injured hippocampus. The data were published in the May 2012 edition of the Journal of Neurosurgery.
