Fig. 1From: Anti-bacterial antibody and T cell responses in bronchiectasis are differentially associated with lung colonization and diseaseAnti-bacterial antibody and T cells responses. Antibody levels against bacterial antigens were measured by ELISA: (a) IgG titres (1/value) against bacteria in BR, COPD and HV groups; (b) Antibody responses against bacteria were compared based on bacterial colonization. T cell responses against bacterial antigens were measured by IFNγ ELIspot: (c) IFNγ spot-forming cells per 106 PBMC against bacteria in BR, COPD and HV groups; (d) IFNγ spot-forming cells per 106 PBMC against bacteria were compared based on bacterial colonization. Anti-pseudomonas Ig subclasses and IgG isotypes in BR (e), COPD (f) and HV (g) subgroups. Mean value + SEM are given. *p < 0.05, ***p < 0.001. Mann-Whitney tests were performedBack to article page
