Drosophila melanogaster antimicrobial defense.
The Drosophila melanogaster host defense is complex but remarkably efficient. It is a multifaceted response to a variety of fungal, bacterial, and parasitic invaders. Current knowledge is discussed on recognition of infectious microorganisms and on the activation of intracellular signaling cascades that concur with the expression of numerous immune-responsive genes, among which, to date, the mo...
متن کاملAncient Anxiety Pathways Influence Drosophila Defense Behaviors
Anxiety helps us anticipate and assess potential danger in ambiguous situations [1-3]; however, the anxiety disorders are the most prevalent class of psychiatric illness [4-6]. Emotional states are shared between humans and other animals [7], as observed by behavioral manifestations [8], physiological responses [9], and gene conservation [10]. Anxiety research makes wide use of three rodent beh...
متن کاملHost Defense via Symbiosis in Drosophila
Host-associated microbes have often been studied as pathogens and the causes of disease, but symbiotic microbes that benefit their hosts are now known to be ubiquitous. In particular, insects possess a diversity of bacteria that can defend against natural enemies—Anopheles mosquitoes, for example, were recently shown to host a gut bacterium that confers refractoriness to malaria parasites [1]. ...
متن کاملThe host defense of Drosophila melanogaster.
To combat infection, the fruit fly Drosophila melanogaster relies on multiple innate defense reactions, many of which are shared with higher organisms. These reactions include the use of physical barriers together with local and systemic immune responses. First, epithelia, such as those beneath the cuticle, in the alimentary tract, and in tracheae, act both as a physical barrier and local defen...
متن کاملEndogenous RNA Interference Provides a Somatic Defense against Drosophila Transposons
BACKGROUND Because of the mutagenic consequences of mobile genetic elements, elaborate defenses have evolved to restrict their activity. A major system that controls the activity of transposable elements (TEs) in flies and vertebrates is mediated by Piwi-interacting RNAs (piRNAs), which are approximately 24-30 nucleotide RNAs that are bound by Piwi-class effectors. The piRNA system is thought t...
