Subject:
pathogens,   etc   ; genes; models;     Show all 3 Subjects
Abstract:
... We propose to integrate the existing and new experimental data with computational tools to model interaction networks for the most prominent kinetoplastid pathogens. These interaction networks will vastly expand the functional annotation of the kinetoplastid genomes, which in turn are critical for identifying new routes of disease intervention. ...

Abstract:
... The NBS-LRR genes are functionally responsible for plant resistance to alien pathogens. Here, we show that NBS-LRR genes originated in the common ancestor of the whole green lineage, and have rapidly diverged into three subclasses with different domain combinations (TNL, CNL, and RNL) before the split of green algae. ...

Subject:
pathogens,   etc   ; immune response; models;     Show all 3 Subjects
Abstract:
... For predictive biology of a large and complex network, important mechanistic information consists of network topology, signal-convergence rules, and signal dynamics. In practice, the key to enabling predictive modeling of a complex network is reducing it sufficiently to allow modeling without omitting important factors affecting network behavior. Here I argue that the plant immune signaling networ ...

Abstract:
... When T cells respond to infectious agents, they differentiate into effector and memory cells. In this issue of Cell, Smith et al. use a genetic “time-stamping” method to show that the developmental time the T cell arises—near birth or as an adult—dictates what type of T effector or memory cell results. ...

Abstract:
... The mammalian immune system includes a sophisticated array of antimicrobial mechanisms. However, successful pathogens have developed subversive strategies to detect, modulate, and/or evade immune control and clearance. Independent disciplines study host immunology and bacterial pathogenesis, but interkingdom signaling between bacteria and host during natural infection remains poorly understood. An ...

Abstract:
... The oyster's immune system is capable of adapting upon exposure to a pathogen-associated molecular pattern (PAMP) to have an enhanced secondary response against the same type of pathogen. This has been demonstrated using poly(I:C) to elicit an antiviral response in the Pacific oyster (Crassostrea gigas) against Ostreid herpesvirus (OsHV-1). Improved survival following exposure to poly(I:C) has bee ...

Abstract:
... Insects are a highly sustainable and nutritious source of protein, and, thus, incorporating insects in to Western food culture is one way to address major global challenges like global warming and deforestation. Consumer studies show, however, that Westerners’ willingness to eat insect-containing food is low. One formidable barrier is the perception that insects are disgusting, and it is generally ...

Abstract:
... The excretion of cytoplasmic and signal-peptide-less proteins (ECP) by microorganisms and eukaryotes remains a fascinating topic. In principle, it appears to be a waste of energy. However, it turns out that – extracellularly – some cytoplasmic proteins (CPs) exert a completely different function such as contributing to pathogenicity or evasion of the immune system. Such CPs have been referred to a ...

Abstract:
... [Display omitted]Pathogens often face zinc restriction due to the action of nutritional immunity – host processes which restrict microbial access to key micronutrients such as zinc and iron. Candida albicans scavenges environmental zinc via two pathways. The plasma membrane transporter Zrt2 is essential for zinc uptake and growth in acidic environments. Neutralisation to pH 7 severely decreases th ...
