Abstract
Sepsis is a dysregulated systemic immune response to infection i.e. responsible for ∼35% of in-hospital deaths at a significant fiscal healthcare cost. Our laboratory, among others, has demonstrated the efficacy of targeting negative checkpoint regulators (NCRs) to improve survival in a murine model of sepsis, cecal ligation and puncture (CLP). B7-CD28 superfamily member, V-domain immunoglobulin suppressor of T cell activation (VISTA), is an ideal candidate for strategic targeting in sepsis. VISTA is a 35 to 45 kDa type 1 transmembrane protein with unique biology that sets it apart from all other NCRs. We recently reported that VISTA-/- mice had a significant survival deficit post-CLP, which was rescued upon adoptive transfer of a VISTA-expressing pMSCV-mouse Foxp3-EF1α-GFP-T2A-puro stable Jurkat cell line (Jurkatfoxp3 T cells). Based on our prior study, we investigated the effector cell target of Jurkatfoxp3 T cells in VISTA-/- mice. γδ T cells are a powerful lymphoid subpopulation that require regulatory fine-tuning by regulatory T cells to prevent overt inflammation/pathology. In this study, we hypothesized that Jurkatfoxp3 T cells nonredundantly modulate the γδ T cell population post-CLP. We found that VISTA-/- mice have an increased accumulation of intestinal CD69low γδ T cells, which are not protective in murine sepsis. Adoptive transfer of Jurkatfoxp3 T cells decreased the intestinal γδ T cell population, suppressed proliferation, skewed remaining γδ T cells toward a CD69high phenotype, and increased soluble CD40L in VISTA-/- mice post-CLP. These results support a potential regulatory mechanism by which VISTA skews intestinal γδ T cell lineage representation in murine sepsis.

Abstract
Immune responses in nonlymphoid tissues play a vital role in the maintenance of homeostasis. Lots of evidence supports that tissue-specific immune cells provide defense against tumor through the localization in different tissue throughout the body, and can be regulated by diverse factors. Accordingly, the distribution of nervous tissue is also tissue-specific which is essential in the growth of corresponding organs, and the occurrence and development of tumor. Although there have been many mature perspectives on the neuroendocrine regulation in tumor microenvironment, the neuroendocrine regulation of tissue-specific immune cells has not yet been summarized. In this review, we focus on how tissue immune responses are influenced by autonomic nervous system, sensory nerves, and various neuroendocrine factors and reversely how tissue-specific immune cells communicate with neuroendocrine system through releasing different factors. Furthermore, we pay attention to the potential mechanisms of neuroendocrine-tissue specific immunity axis involved in tumors. This may provide new insights for the immunotherapy of tumors in the future.

Abstract
BACKGROUND Neuroimmune communication plays an important role in allergic inflammation, but the neuroimmune regulation of allergic rhinitis remains unclear. OBJECTIVE The goal of this study was to investigate the role of CD4-positive T lymphocyte (CD4+ T cells) adhesion to D-U87 neuron-like cells in mediating allergic rhinitis CD4+ T cell differentiation. METHODS D-U87 neuron-like cells were derived from the human glioblastoma U87 cell line. CD4+ T cells were isolated from human peripheral blood using a magnetic separation technique. In vitro coculture of D-U87 neuron-like cells and CD4+ T cells was established. The number of adherent CD4+ T cells was counted using a fluorescence microscope. The percentages of CD4+IFNγ+ and CD4+IL4+ T cells and the levels of IFNγ and IL4 cytokines in the supernatant were measured by flow cytometry. RESULTS The results showed that the number of adherent CD4+ T cells in patients with allergic rhinitis was significantly higher than that in healthy controls. In allergic rhinitis, the percentage of CD4+IL4+ T cells was significantly increased in the adherent group compared with that in the nonadherent group. Moreover, blocking ICAM1 and E-selectin decreased the number of adherent CD4+ T cells and the percentage of CD4+IL4+ T cells in allergic rhinitis. CONCLUSION Adhesion contributes to CD4+IL4+ T cell differentiation in the in vitro coculture system of D-U87 neuron-like cells and allergic rhinitis CD4+ T cells, which may provide new insights into therapeutic strategies for allergic rhinitis.

Abstract
The neural and immune systems are closely connected, and recently, their molecular mechanisms and relationships with diseases have attracted substantial attention. Particularly, it has been increasingly reported that ILC2s, which produce type 2 cytokines independent of acquired immunity, are regulated by neuropeptides such as catecholamines, acetylcholine, vasoactive intestinal peptide, neuromedins, and calcitonin gene-related peptide. However, the regulatory mechanisms in this regard are only partially understood, implying that further studies are still needed to clarify the complete mechanisms and processes. In this review, we summarize current reports on the regulatory effect of neuropeptides on ILC2s, some of which have conflicting results, possibly owing to the complexity of G-protein coupled receptors. By summarizing the current evidence, we hope to be able to identify what is currently unknown as well as what needs to be clarified in the future.

Abstract
Neuromedin U (NMU) is a regulatory peptide that is widely distributed throughout the body and performs a variety of physiological functions through its corresponding receptors. In recent years, NMU has become the focus of attention in various fields of research as its diverse and essential functions have gradually been elucidated. However, there have been no bibliometrics studies on the development trend and knowledge structure of NMU research. Therefore, in this study, we used VOSviewer software to statistically analyze scientific data from articles related to NMU to track the developmental footprint of this research field, including relevant countries, institutions, authors, and keywords. We retrieved a total of 338 papers related to NMU, written by 1,661 authors from 438 organizations of 41 countries that were published in 332 journals. The first study on NMU was reported by a group in Japan in 1985. Subsequently, nine articles on NMU were published from 1987 to 2006. A small leap in this field could be detected in 2009, with 30 articles published worldwide. Among the various countries in which this research has been performed, Japan and the United States have made the most outstanding contributions. Miyazato M, Kangawa K, and Mori K from the Department of Biochemistry, National Retrain and Cardiovascular Center Research Institute in Japan were the most productive authors who have the highest number of citations. Keyword analysis showed six clusters: central-nervous-system, homeostasis, energy metabolism, cancer, immune inflammation, and food intake. The three most highly cited articles were associated with inflammation. Overall, this study demonstrates the research trends and future directions of NMU, providing an objective description of the contributions in this field along with reference value for future research.

Abstract
Innate lymphoid cells (ILCs) are a heterogeneous group of cytokine-producing lymphocytes which are predominantly located at mucosal barrier surfaces, such as skin, lungs, and gastrointestinal tract. ILCs contribute to tissue homeostasis, regulate microbiota-derived signals, and protect against mucosal pathogens. ILCs are classified into five major groups by their developmental origin and distinct cytokine production. A recently emerged intriguing feature of ILCs is their ability to alter their phenotype and function in response to changing local environmental cues such as pathogen invasion. Once the pathogen crosses host barriers, ILCs quickly activate cytokine production to limit the spread of the pathogen. However, the dysregulated ILC responses can lead to tissue inflammation and damage. Furthermore, the interplay between ILCs and other immune cell types shapes the outcome of the immune response. Recent studies highlighted the important role of ILCs for host defense against intracellular pathogens. Here, we review recent advances in understanding the mechanisms controlling protective and pathogenic ILC responses to intracellular pathogens. This knowledge can help develop new ILC-targeted strategies to control infectious diseases and immunopathology.
