ABSTRACT
AIMS:
Immunization with neural-derived peptides (INDP) has demonstrated to be a promising therapy to achieve a regenerative effect in the chronic phase of the spinal cord injury (SCI). Nevertheless, INDP-induced neurogenic effects in the chronic stage of SCI have not been explored. METHODS ANDRESULTS:
In this study, we analyzed the effect of INDP on both motor and sensitive function recovery; afterward, we assessed neurogenesis and determined the production of cytokines (IL-4, IL-10, and TNF alpha) and neurotrophic factors (BDNF and GAP-43). During the chronic stage of SCI, rats subjected to INDP showed a significant increase in both motor and sensitive recovery when compared to the control group. Moreover, we found a significant increase in neurogenesis, mainly at the central canal and at both the dorsal and ventral horns of INDP-treated animals. Finally, INDP induced significant production of antiinflammatory and regeneration-associated proteins in the chronic stages of SCI.CONCLUSIONS:
These findings suggest that INDP has a neurogenic effect that could improve motor and sensitive recovery in the chronic stage of SCI. Moreover, our results also envision the use of INDP as a possible therapeutic strategy for other trauma-related disorders like traumatic brain injury.Palabras clave
