Interestingly, animals ZK38 and ZL43 which experienced no weight loss, the lowest PET hot signals and the largest CD4 T cell reactions in the airways also experienced the largest CD4 T cell reactions in individual granulomas

Interestingly, animals ZK38 and ZL43 which experienced no weight loss, the lowest PET hot signals and the largest CD4 T cell reactions in the airways also experienced the largest CD4 T cell reactions in individual granulomas. Mtb-specific CD4 T cells simultaneously appeared in the airways and blood ~21C28 days post-exposure, Continue Reading
