Antigen-Specific Tissue-Resident Memory T Cells in the Respiratory System Were Generated following Intranasal Vaccination of Mice with BCG

Figure 1

Vaccination of mice with BCG induced the production and expression of IFN-γ by T cells in the lavage fluids, nasal mucosa, trachea, and lungs. (a) Scheme of immunization. (b) Respiratory system tissues of lavage fluids nasal mucosa, trachea, lung, and blood cells were stimulated for 48 hrs with or without BCG plus anti-CD28 in the plate. The culture supernatants were detected for the production of INF-γ by ELISA. (c) The levels of IFN-γ in plasma, BALF, and NLF were detected by ELISA as . Statistical significance was determined with two-way ANOVA. and ; ns: no significance.
