Naturally acquired immunity to falciparum malaria protects millions of people routinely exposed to Plasmodium falciparum infection from severe disease and death. There is no clear concept about how this protection works. There is no general agreement about the rate of onset of acquired immunity or what constitutes the key determinants of protection; much less is there a consensus regarding the ...
متن کاملInnate and acquired immunity
• The cells of the immune system are divided into lymphoid and myeloid lineages. The former include T lymphocytes and their subsets identified by CD markers, B lymphocytes and natural killer (NK) cells. The myeloid lineage includes the neutrophils, eosinophils and basophils as well as the monocyte/ macrophage series and platelets. • Innate immunity depends on physical, physiological and chemica...
متن کاملEicosanoid actions in insect immunity.
Insects express 3 lines of protection from infections and invasions. Their cuticles and peritrophic membranes are physical barriers. Infections and invasions are quickly recognized within insect bodies, and recognition launches 2 lines of innate immune reactions. Humoral reactions involve induced synthesis of antimicrobial peptides, the bacteriolytic enzyme lysozyme and activation of the prophe...
متن کاملPlant immunity to insect herbivores.
Herbivorous insects use diverse feeding strategies to obtain nutrients from their host plants. Rather than acting as passive victims in these interactions, plants respond to herbivory with the production of toxins and defensive proteins that target physiological processes in the insect. Herbivore-challenged plants also emit volatiles that attract insect predators and bolster resistance to futur...
متن کاملInsect immunity: from pattern recognition to symbiont-mediated host defense.
The Jacques Monod conference "Insect Immunity in Action: From Fundamental Mechanisms of Host Defense to Resistance Against Infections in Nature," organized by Ulrich Theopold (Stockholm University, Sweden) and Dominique Ferrandon (CNRS, France), was held in May 2009 in Aussois, France. Here, we review key topics and concepts that were presented and highlight emerging trends in the field of inse...
