A functional screen for ubiquitin regulation identifies an E3 ligase secreted by .

Ubiquitin signaling controls many aspects of eukaryotic biology, including targeted protein degradation and immune defense. Remarkably, invading bacterial pathogens have adapted secreted effector proteins that hijack host ubiquitination to gain control over host responses. These ubiquitin-targeted effectors can exhibit, for example, E3 ligase or deubiquitinase activities, often without any sequence or structural homology to eukaryotic ubiquitin regulators.

The effects of multifactorial stress combination on rice and maize.

The complexity of environmental factors affecting crops in the field is gradually increasing due to climate change-associated weather events, such as droughts or floods combined with heat waves, coupled with the accumulation of different environmental and agricultural pollutants. The impact of multiple stress conditions on plants was recently termed "multifactorial stress combination" (MFSC) and defined as the occurrence of 3 or more stressors that impact plants simultaneously or sequentially. We recently reported that with the increased number and complexity of different MFSC stressors, the growth and survival of Arabidopsis (Arabidopsis thaliana) seedlings declines, even if the level of each individual stress is low enough to have no significant effect on plants.

Effect of Renal Impairment on the Pharmacokinetics of a Single Oral Dose of Danuglipron in Participants With Type 2 Diabetes.

Danuglipron (PF-06882961) is an oral, small-molecule glucagon-like peptide-1 receptor agonist in development for the treatment of type 2 diabetes (T2D) and obesity. Impaired renal function is prevalent in patients with T2D. This Phase 1, open-label study evaluated the effect of renal impairment on the pharmacokinetics, safety, and tolerability of danuglipron (20 mg) in healthy participants with normal renal function (estimated glomerular filtration rate [eGFR] unnormalized for body surface area: ≥90 mL/min), in participants with T2D and normal renal function (eGFR ≥90 mL/min), and in participants with T2D and mild (eGFR 60-89 mL/min), moderate (eGFR 30-59 mL/min), or severe (eGFR <30 mL/min) renal impairment (N = 39).

CD200R1 promotes interleukin-17 production by group 3 innate lymphoid cells by enhancing signal transducer and activator of transcription 3 activation.

Psoriasis is a common chronic inflammatory skin disease with no cure. It is driven by the interleukin (IL)-23/IL-17A axis and type 17 T helper cells; however, recently, group 3 innate lymphoid cells (ILC3s) have also been implicated. Despite being the focus of much research, factors regulating the activity of ILC3s remain incompletely understood.

Combined influence of valence and statistical learning on the control of attention II: Evidence from within-domain additivity.

Attention is biased in favor of stimuli that signal either threat or reward; this experience-dependent attentional bias develops via associative learning and persists into extinction. Physically salient yet task-irrelevant stimuli are also prioritized by the attention system, but the attentional priority of a physically salient distractor can be suppressed when it appears in a location in which it has been frequently encountered in the past. Similar effects of statistical learning on distractor suppression have been observed for distractors appearing in a predictable color.
