Deep profiling deconstructs features associated with memory CD8 T cell tissue residence.

Tissue-resident memory CD8 T (Trm) cells control infections and cancer and are defined by their lack of recirculation. Because migration is difficult to assess, residence is usually inferred by putative residence-defining phenotypic and gene signature proxies. We assessed the validity and universality of residence proxies by integrating mouse parabiosis, multi-organ sampling, intravascular staining, acute and chronic infection models, dirty mice, and single-cell multi-omics.

Molecular basis for plasma membrane recruitment of PI4KA by EFR3.

The lipid kinase phosphatidylinositol 4 kinase III α (PI4KIIIα/PI4KA) is a master regulator of the lipid composition and asymmetry of the plasma membrane. PI4KA exists primarily in a heterotrimeric complex with its regulatory proteins TTC7 and FAM126. Fundamental to PI4KA activity is its targeted recruitment to the plasma membrane by the lipidated proteins EFR3A and EFR3B.

Exacerbation of neuropsychiatric symptoms in an adult male with influenza A virus treated with oseltamivir.

Oseltamivir (Tamiflu) package labeling has a warning for neuropsychiatric adverse events (NPAE), most commonly in children and adolescents, especially males. There are several case reports of NPAE in adults treated with oseltamivir, but few document patients with preexisting neuropsychiatric conditions without additional contributing factors. This case report describes a 22-year-old male with a history of bipolar disorder, depression, and attention-deficit/hyperactivity disorder who had been stable on his medication regimen before experiencing sudden worsening of symptoms after the initiation of oseltamivir.

Optimising aerial herbicide treatment for control of dense conifer infestations: a New Zealand case study.

Background: Conifers, mainly of the genus Pinus, have invaded natural and productive landscapes worldwide. Controlling dense conifer invasions is challenging and requires both effective initial control methods and long-term site management to prevent re-invasion. Broadcast aerial herbicide application is often the preferred treatment method for dense infestations of pines with high rates of complex herbicide mixtures used.

Visual Field Asymmetries in Responses to ON and OFF Pathway Biasing Stimuli.

Recent reports suggest the ON and OFF pathways are differentially susceptible to selective vision loss in glaucoma. Thus, perimetric assessment of ON- and OFF-pathway function may serve as a useful diagnostic. However, this necessitates a developed understanding of normal ON/OFF pathway function around the visual field and as a function of input intensity.
