Injeção subcutânea de antígeno bacteriano para induzir inflamação sistêmica em modelo murino

Executive Industry Relevance

Inducing systemic inflammation in murine models via subcutaneous injection of mycobacterial antigen-adjuvant depots enables controlled interrogation of immune activation pathways relevant to post-infectious inflammatory diseases. This approach provides a reproducible platform for evaluating immune cell recruitment, cytokine release, and systemic inflammatory responses, supporting early-stage target validation and mechanistic de-risking in immunology-focused drug discovery. The model's translational relevance to post-infectious uveitis enhances its value for portfolio triage and preclinical candidate assessment.
