Interleukin (IL)-22 is central to immune defense at barrier sites. We examined the contributions of innate lymphoid cell (ILC) and T cell-derived IL-22 during Citrobacter rodentium (C.r) infection using mice that both report Il22 expression and allow lineage-specific deletion. ILC-derived IL-22 activated STAT3 in C.r-colonized surface intestinal epithelial cells (IECs) but only temporally restrained bacterial growth. T cell-derived IL-22 induced a more robust and extensive activation of STAT3 in IECs, including IECs lining colonic crypts, and T cell-specific deficiency of IL-22 led to pathogen invasion of the crypts and increased mortality. This reflected a requirement for T cell-derived IL-22 for the expression of a host-protective transcriptomic program that included AMPs, neutrophil-recruiting chemokines, and mucin-related molecules, and it restricted IFNγ-induced proinflammatory genes. Our findings demonstrate spatiotemporal differences in the production and action of IL-22 by ILCs and T cells during infection and reveal an indispensable role for IL-22-producing T cells in the protection of the intestinal crypts.The immune system is a complex, dynamic, and plastic ecosystem composed of multiple cell types that constantly sense and interact with their local microenvironment to protect from infection and maintain homeostasis. For over a century, great efforts and ingenuity have been applied to the characterization of immune cells and their microenvironments, but traditional marker-based and bulk technologies left key questions unanswered. In the past decade, the advent of single-cell genomic approaches has revolutionized our knowledge of the cellular and molecular makeup of the immune system. In this perspective, we outline the past, present, and future applications of single-cell genomics in immunology and discuss how the integration of multiomics at the single-cell level will pave the way for future advances in immunology research and clinical translation.Epstein-Barr virus (EBV) is a putative trigger for multiple sclerosis (MS), but clear causality is lacking. selleck inhibitor In a recent issue of Science, Bjornevik and Cortese et al. utilize longitudinal evaluation of over 10 million adults to demonstrate increased MS risk after EBV infection.In this issue of Immunity, Meylan et al. (2022) uses spatial transcriptomics to examine B cell immunity within intratumoral tertiary lymphoid structures (TLSs). They find that B cells expand and mature into plasma cells (PCs) within the TLS, migrate along fibroblastic tracks to tumor beds, and produce IgG antibodies that target cancer cells.Some bacteria and parasites, such as Salmonella, actively disrupt germinal centers and elicit only low affinity antibodies, but the mechanisms by which microbes alter these responses is poorly understood. In this issue of Immunity, Biram et al. (2022) uncover a mechanism by which Salmonella recruits Sca-1+ monocytes to germinal centers and impairs metabolic adaptation.Macrophage activation is essential for effective immunity to infection but can also contribute to disease through incompletely understood mechanisms. In this issue of Immunity, Simpson et al. reveal that death of activated macrophages integrates extrinsic and intrinsic pathways of apoptosis that contribute to damaging host responses.The presumed common origin of plasmacytoid and conventional dendritic cells has been the contentious subject of recent debate. In this issue of Immunity, Feng et al. employed an inducible cell barcoding system to track clonal relationships and uncovered a surprising close developmental relationship between cDC1s and pDCs.Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens on habitat integrity and connectivity for conservation and human health; a global network of animal sentinels of environmental change.Hyperpigmentation of the tongue has been associated with chemotherapy, specifically cytotoxic drugs, but the exact pathophysiological mechanism is still not well understood. We describe a 37-year-old black woman that presented with tongue hyperpigmentation one week after the initiation of chemotherapy with temozolomide as a single agent. No cases of tongue hyperpigmentation associated with temozolomide as a single agent have been reported before. The diagnosis of drug associated pigmentary changes is based on the confirmation the onset of the clinical observations shortly after the initiation of the chemotherapy agent. The tongue hyperpigmentation is usually self-limited. This case constitutes a challenge for healthcare professionals and patients and emphasizes the importance of documenting these cases in order to guide healthcare professionals in managing the expectations of the patients and the potential adverse effects associated with certain drugs.A case of monkeypox was diagnosed in a returning traveler from Nigeria to Maryland, USA. Prompt infection control measures led to no secondary cases in 40 exposed healthcare workers. Given the global health implications, public health systems should be aware of effective strategies to mitigate the potential spread of monkeypox.

Practitioners can be reassured that this antihistamine-releasing contact lens has no additional effect on corneal epithelial integrity.

To evaluate the effect of an antihistamine-releasing soft contact lens on corneal epithelium integrity when worn on a daily disposable modality for 12weeks.

Two clinical trials using the same randomised, double-masked, placebo-controlled, parallel-group design enrolled healthy contact lens wearers. Participants wore either etafilcon A with 0.019 mg ketotifen (test; n =374) or etafilcon A with no added drug (placebo; n =186). Assessments were conducted at baseline, 1week and 4, 8, and 12weeks. Slit-lamp evaluations of corneal staining (using sodium fluorescein) in all regions of the corneas of both eyes were graded on a 0-4 scale. Data from all randomised participants were analysed.

Corneal staining was infrequent and, where present, was mild (Grade 2) or trace (Grade 1). There were no Grade 3 or 4 findings of corneal staining. The overall proportion of findings of Grade 0 corneal staining was 95.86% with the test lens and 95.88% with the placebo lens. The odds of no staining were not statistically different between the test and placebo lenses (Odds Ratio 0.96, 95% Confidence Intervals 0.76 to 1.20). There were no serious ocular adverse events or signs of ocular surface medicamentosa.

Both test and placebo lenses were well tolerated by subjects during the 3months of wear. The antihistamine-releasing contact lens does not significantly impact corneal epithelial integrity.

RT-qPCR was performed to analyze SNHG1, microRNA (miRNA)-181a-5p, and PTEN levels. ROC curves were used to detect the predictive value of SNHG1 for delayed healing in fracture patients. Subsequently, the regulation of osteogenic markers by SNHG1 and miR-181a-5p was analyzed in MC3T3-E1. Cell proliferation and apoptosis were quantified by CCK-8 and flow cytometry. The binding between SNHG1/miR-181a-5p/PTEN was detected by dual-luciferase reporter gene assay.Results Serum SNHG1 and PTEN expression were upregulated and miR-181a-5p expression was downregulated in patients with delayed fracture healing. SNHG1 decreased the level of osteogenic markers in MC3T3-E1, inhibited the proliferation, and stimulated apoptosis of MC3T3-E1 (P  less then  0.05). SNHG1 acted as a sponge for miR-181a-5p, and elevation of miR-181a-5p abolished the inhibition of osteogenic differentiation and promotion of apoptosis by SNHG1 (P  less then  0.05). PTEN was identified as a target of miR-181a-5p and involved in this regulatory process. Finally, elevated SNHG1 was a feasible predictive biomarker in patients with delayed fracture healing.Conclusion The current study revealed that SNHG1/miR-181a-5p/PTEN axis inhibited osteoblast differentiation and proliferation and promoted apoptosis, thus leading to the inhibition of tibial fracture healing. Our findings contribute to the understanding of the mechanisms underlying delayed tibial fracture healing.

The purpose of this letter is to address interpretations regarding Bambara et al.'s (2021) study and help resolve potential for further missteps within this line of research.

There is clear value in teaching skills that are wanted by autistic people. The primary issue within the article is that it does not acknowledge the double empathy problem and is constructed based on only a neurotypical system of interpretation or communication style. What is being promoted is to address skills autistic participants request.

The purpose of this letter is to draw attention to recent literature regarding the communication abilities and experiences of Autistic people and the potential for detrimental effects on mental health and service provision resulting from behavior modification programs. I will argue that viewing Autistic communication as characterized by pragmatic language impairment is inconsistent with evidence of effective and positive communication between Autistic people and with the social model of disability.

Proposals for interventions targeting Autistic people should carefully weigh the costs and benefits for Autistic people and should integrate the perspectives of Autistic people.

Impaired stereoacuity is seen in some children without amblyopia, strabismus, and clinically significant refractive errors. Therefore, there are probably other factors affecting stereoacuity.

The aim of this work was to investigate the longitudinal changes of local stereoacuity and associated factors in schoolchildren.

The present report is a part of the Shahroud Schoolchildren Eye Cohort Study. The target population was children aged 6 to 12years in Shahroud, Iran. The second phase of the study was conducted in 2018 by re-inviting all participants in the first phase (2015). After an initial interview, study participants underwent optometric examination and ocular biometry. Stereoacuity was evaluated using Stereo Fly Test. Exclusion criteria were functional amblyopia, strabismus, significant refractive errors, probable ocular pathology/organic amblyopia in either of the two study phases, a history of intraocular surgery or ocular trauma, and incomplete data.

The data of 4666 children were analysed for this report, of which 53.
