This invention provides lactylated PRDX5
protein, its products, and applications, belonging to the field of
biomedical technology. This invention reveals the crucial role of PRDX5 K71 site lactylation modification in the
pathological process of
COPD, showing abnormally elevated levels of lactylation in hippocampal neurons of
COPD mice, which is closely related to the occurrence and development of
cognitive impairment in mice. Simultaneously, it provides a specific intervention protocol targeting this site. Stereoscopic injection of recombinant adeno-associated
virus PRDX5 K71R
mutant reduces or blocks the likelihood of lactylation modification at the K71 site, effectively improving learning, memory, and spatial orientation abilities in
COPD mice. This provides new
molecular targets and experimental evidence for the study of the mechanisms of
cognitive impairment and targeted prevention and treatment.
