Antifungal Host Defense Peptides
Fungi infect billions of people every year, yet their contribution to the global burden of disease is largely unrecognized and the repertoire of antifungal agents is rather limited. Thus, treatment of life-threatening invasive fungal infections is still based on drugs discovered several decades ago. In addition, recent data on resistance emergence of fungi emphasize the urgent need for novel an...
متن کاملPulmonary host defense mechanisms.
T he major function of the respiratory system is to procure oxygen from the external environment and to eliminate carbon dioxide from the body at rates required by tissue metabolism. Unfortunately, ambient inspired air contains not only oxygen which is vital to survival, but also noxious gases and a multitude of particulates, including viable microorganisms, which the lungs must exclude to main...

متن کاملHost defense reinforces host-parasite cospeciation.
Cospeciation occurs when interacting groups, such as hosts and parasites, speciate in tandem, generating congruent phylogenies. Cospeciation can be a neutral process in which parasites speciate merely because they are isolated on diverging host islands. Adaptive evolution may also play a role, but this has seldom been tested. We explored the adaptive basis of cospeciation by using a model syste...
متن کاملTranscript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
