Tuftsin-phosphorylcholine attenuate experimental autoimmune encephalomyelitis.

Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS) which carries a significant burden of morbidity and mortality. Herein we examine the effects of acute treatment with tuftsin-phosphorylcholine (TPC), a novel immune-modulating helminth derived compound, on a murine model of MS. Experimental autoimmune encephalomyelitis (EAE) mice received acute treatment with TPC showed an improved clinical score and significantly less signs of inflammation and demyelination in CNS tissue compared with vehicle treated EAE mice.

Effect of short peptides on neuronal differentiation of stem cells.

It has been demonstrated that short peptides play an important role in the transmission of biological information, modulation of transcription, and restoring genetically conditioned alterations occurring with age. Peptidergic regulation of homeostasis occupies an important place in physiological processes, which lead to the aging of cells, tissues, and organs, consisting in the involution of major regulatory systems-the nervous, the endocrine, and the immune. The effect of AED (Ala-Glu-Asp), KED (Lys-Glu-Asp), KE (Lys-Glu), AEDG (Ala-Glu-Asp-Gly) peptides and their compound on neuronal differentiation of human periodontal ligament stem cells (hPDLSCs) was studied by immunofluorescence and western blot analysis.
