Dataset Summary
| Title | Differential proteome profiling of bacterial culture supernatants reveals candidates for the induction of oral immune priming in the Red Flour Beetle |
| Description | Most organisms are hosts to a wide range of symbionts and commensals, but they might also encounter parasites and pathogens during their lifetime. Therefore, immune strategies to recognize and counteract potential threats have evolved across all kingdoms of life. The most elaborate immune defences are found in vertebrate animals, where responses are classically divided into innate and adaptive. Insects lack the cellular machinery needed to provide adaptive immunity. However, over the past decades, work on immune priming has shown that to a certain degree, insects are indeed capable of specifically recognizing, memorizing, and counteracting certain pathogens. An important piece of the puzzle are the pathogen-associated molecules that induce these immune priming responses. Here, we make use of the model system Tribolium castaneum (T. castaneum) and its pathogen Bacillus thuringiensis (B. thuringiensis), to compare the proteomes of two closely related B. thuringiensis strains that either induce priming via the oral route, or not. We identify proteins that might be immunostimulatory in T. castaneum. The Cry3Aa toxin, an important plasmid-encoded virulence factor of Bacillus thuringiensis bv. tenebrionis (hereafter called Btt) was found to be one of the most promising candidates. We made use of additional B. thuringiensis strains varying in the possession of the Cry-carrying plasmid to experimentally test for its relevance for priming. Our findings will help future studies to focus on specific candidates to perform experiments on the mechanisms and evolution of immune priming. |
