基于 CRISPR 干扰的基因沉默:一种靶向抑制致病性钩端螺旋体基因功能的技术

Executive Industry Relevance

CRISPR interference (CRISPRi) enables targeted gene repression in pathogenic Leptospira, providing a precise tool for functional genomics in early discovery. This approach supports mechanistic de-risking and target validation by allowing direct interrogation of gene function in a disease-relevant bacterial system. Its integration into the discovery pipeline enhances predictive confidence for downstream pharmacological studies.

Strategic Applications in Biopharma R&D
