Functional characterization of Drosophila melanogaster immune effectors

Alexia Laurie Carboni

Drosophila melanogaster, commonly known as the "fruit fly", is a genetically tractable model organism widely used to study biological processes, notably the innate immune system. The advent of novel genome editing technologies, such as the CRISPR-Cas9 syst ...

Antimicrobial peptides (AMPs) are host-encoded antibiotics that combat invading microbes. These short immune effectors are conserved in plants, animals, and fungi. Early work showed that AMPs killed bacteria in generalist fashions in vitro: i.e. AMPs that ...

All metazoan guts are subject to opposing pressures wherein the immune system must eliminate pathogens while tolerating the presence of symbiotic microbiota. The Imd pathway is an essential defense against invading pathogens in insect guts, but tolerance m ...

All live beings are in constant interaction with microorganisms that may be beneficial, deleterious or commensal. Insects in particular live in close contact with microorganisms. This is especially true for species, like the fruit fly Drosophila melanogast ...

The body is home to a diverse microbiota, mainly in the gut. Resistant bacteria are selected by antibiotic treatments, and once resistance becomes widespread in a population of hosts, antibiotics become useless. Here, we develop a multiscale model of the i ...

Much has been learned about the genetics of aging from studies in model organisms, but still little is known about naturally occurring alleles that contribute to variation in longevity. For example, analysis of mutants and transgenes has identified insulin ...

Several embodiments of the present disclosure relate to therapeutic compositions configured to target the liver of a subject and that are useful in the treatment or prevention of one or more of transplant rejection, autoimmune disease, food allergy, and im ...

Background: Members of the thioester-containing protein (TEP) family contribute to host defence in both insects and mammals. However, their role in the immune response of Drosophila is elusive. In this study, we address the role of TEPs in Drosophila immun ...

Sirtuin 3 (SIRT3) is the main mitochondrial deacetylase. SIRT3 regulates cell metabolism and redox homeostasis, and protects from aging and age-associated pathologies. SIRT3 may drive both oncogenic and tumor-suppressive effects. SIRT3 deficiency has been ...

Creative strategies for identifying new antibiotics are essential to addressing the looming threat of a post-antibiotic era. We here report the use of a targeted peptide phage display screen as a means of generating novel antimicrobial lipopeptides. Specif ...
