RNA seq analysis from the kidney neutrophils of pycard mutant adult zebrafish in Mycobacterium marinum infection


ABSTRACT: Inflammasome regulates the host response to intracellular pathogens including mycobacteria. We have previously shown that the course of M. marinum infection in adult zebrafish (Danio rerio) has similar features than the course of tuberculosis in human. Here we have investigated the role of the inflammasome adaptor pycard in M. marinum infection in zebrafish with two CRISPR/Cas9 mutagenesis generated zebrafish line. Adult zebrafish devoid of pycard showed impaired survival and increased bacterial burden in M. marinum infection. Transcriptome analysis with RNA sequencing of a kidney derived neutrophils of M. marinum infected fish homozygous for pycardptu4 mutation revealed differentially expressed genes compared to WT controls. Differentially expressed genes were associated with neutrophil degranulation, haematopoiesis and PI3K signalling are differentially expressed in the pycard deficient neutrophils when compared to wild type controls.
