Host neural and tissue repair pathways

Host neural and tissue repair pathways refer to the collective endogenous mechanisms that the body utilizes to restore structural integrity and physiological function following injury or disease. These pathways are particularly critical in the nervous system, where they encompass processes such as neurogenesis, axonal regrowth, and synaptic plasticity (Cramer et al., 2011, Lancet). In many pathological states, such as spinal cord injury or stroke, these repair pathways are actively suppressed by inhibitory molecules like chondroitin sulfate proteoglycans (CSPGs) found in the glial scar (Silver & Miller, 2004, Nature Reviews Neuroscience). Therapeutic strategies often focus on neutralizing these inhibitors or providing neurotrophic support to re-engage the host's innate regenerative capacity. Because this term describes a broad set of biological processes rather than a specific molecular entity like a receptor or enzyme, it is not classified as a discrete therapeutic target. Instead, it serves as a functional category for various molecular targets, such as PTPσ, that contribute to the overarching goal of tissue restoration (NervGen Pharma, 2023).
