Executive Industry Relevance

Quantifying immune cell infiltration in infected tissues provides critical data for target validation in infectious disease research. Flow cytometry enables precise measurement of immune responses, supporting mechanistic de-risking and predictive confidence in preclinical models. This approach aids in evaluating therapeutic hypotheses and prioritizing candidates in urinary tract infection programs.
