The high heterogeneity of tumor cells and the surrounding immune microenvironment affects the response to treatment in colorectal cancer (CRC) patients. Therefore, there is a need to identify new immune biomarkers to predict the treatment efficacy of CRC. This study aimed to explore the predictive value of tumor-infiltrating lymphocytes (TIL) for survival in CRC patients. Flow cytometry and gated analysis were performed to measure the TILs in tissue samples obtained from 536 CRC patients. The COX regression analysis showed that the CD8 + CD279+ cells had the highest impact of all evaluated TILs on postoperative disease-free survival (DFS) (P less then 0.05). The optimal CD8 + CD279+ cutoff point for the prediction of survival was 12.2%. The Kaplan-Meier analysis showed significantly higher DFS in the high CD8 + CD279+ group compared with the low CD8 + CD279+ group (P less then 0.05). CD8 + CD279+ cells were associated with DFS in CRC patients with the KARS mutation, MSI/MMR, perineural invasion, and those treated with neoadjuvant chemotherapy and other chemotherapeutic treatments (P less then 0.05). After the multivariate adjustment, the expression of CD8 + CD279+ remained an independent risk factor for DFS. Overall, the CD8 + CD279+ cells were identified as an independent prognostic factor in CRC patients and could be used as a potential marker for postoperative DFS.Respiratory syncytial virus (RSV) infection induces the activation of CD4+ T cells. However, the underlying mechanism of CD4+T-cell activation induced by RSV infection is not fully understood. In the present study, we found that depletion of CD4+ T cells can obviously reduce airway inflammation caused by RSV infection. Meanwhile, adoptive transfer of group 2 innate lymphocytes (ILC2s) significantly enhanced the number of CD4+ T cells and promoted their differentiation to Th2 in lung. In fact, RSV infection increased the expression of major histocompatibility complex-II (MHC II) molecules on the surface of pulmonary ILC2s. In vitro coculture experiments showed that ILC2s may act as promoters to promote the expansion and differentiation of RSV-infected CD4+ T cells. However, blocking the interaction between CD4+ T cells and ILC2s with anti-MHC-II mAbs significantly reduced CD4+T-cell expansion. These results suggest that pulmonary ILC2s may function as antigen-presenting cells to induce the activation of CD4+ T cells through the MHC II pathway during RSV infection.Doxorubicin (DOX), a broad-spectrum anti-tumor drug, has severe cardiotoxic side effects that limit its clinical application. Perillaldehyde (PAE) is the main component of volatile oil extracted from the stems and leaves of Herbaceous plant-perilla, which demonstrates antioxidant, anti-inflammatory, hypolipidemic, and other health functions. The present study aimed to explore the protective effect of perillaldehyde on DOX-induced cardiotoxicity in rats and to confirm its possible mechanism. selleck chemicals llc The results showed that PAE could significantly improve cardiac function, alleviate myocardial fibrosis, and attenuate oxidative stress and inflammatory responses in DOX-induced cardiotoxicity in rats. Mechanistically, PAE could DOX-induced cardiotoxicity, which is related to its regulation of the PI3K/Akt signaling pathway and inhibition of NHE1 phosphorylation. Therefore, the finding demonstrates that perillaldehyde may be a promising cardioprotective agent for the prevention and treatment of cardiotoxicity caused by DOX.During the Rituximab era, high dose intravenous methotrexate (HD) and intrathecal methotrexate (IT) are recommended prophylaxis in preventing central nervous system (CNS) relapse of diffuse large B-cell lymphoma (DLBCL) patients. However, the optimal CNS prophylaxis strategies remained uncertain. This meta-analysis research explored the findings of previous studies and highlighted the efficacy of HD and/or IT on CNS prophylaxis of DLBCL patients at intermediate to high risk. Specifically, it aims to answer the following research questions (1) Is there a difference on CNS relapse rate between HD and IT cohorts? (2) Is there a correlation between CNS prophylaxis and survival? This meta-analysis research performed an in-depth examination of pertinent studies available in PubMed, Embase, and Cochrane databases. The primary endpoints included CNS relapse rate and 2-year or 3-year survival rate. The findings of the qualified studies were reviewed and analyzed using 5.3 version of the Review Manager software. After thorough analysis of 12 studies involving 5950 DLBCL patients, it was revealed that in comparison with IT alone, HD with or without additional IT (HD ± IT) significantly reduced the risk of CNS relapse (Risk Ratio (RR)= 0.41, 95 % CI (0.24-0.68), P = 0.0007). Besides, the efficacy of HD alone was comparable to HD + IT (RR = 1.08, 95 % CI (0.19-6.32), P = 0.93), which was also considered to be more optimal than IT alone on CNS prophylaxis (RR = 0.39, 95 % CI (0.15-1.06), P = 0.06).Based on these results, IT alone or no-prophylaxis were viewed as a group of inadequate prophylaxis. Comparing to HD ± IT, the 3-year survival rate of inadequate prophylaxis group was lower (RR = 1.17, 95 % CI (1.03-1.32), P = 0.01). The results of this study reveals that in the Rituximab Era, prophylaxis strategies containing HD is better than IT alone or no-prophylaxis on preventing CNS relapse of DLBCL patients with intermediate to high risk.Myeloid-derived suppressor cells (MDSCs), a population derived from immature myeloid progenitors, are present in the tumors of patients and highly protumorigenic. However, the molecular mechanisms regulating MDSC infiltration remain unclear. Neddylation pathway is overactivated in multiple cancers and has a significant role in tumor progression. We established a subcutaneous transplantation model of Lewis lung cancer in mice and showed that inactivation of neddylation pathway inhibits MDSC infiltration and impairs lung cancer growth. A high expression level of neuronal precursor cell-expressed developmentally downregulated protein 8 (NEDD8) is positively correlated with MDSC infiltration in human lung adenocarcinomas (LUADs). Moreover, inactivation of neddylation pathway inhibits the expression of murine CXCL5 (mCXCL5; human homolog CXCL6, hCXCL6), an important cytokine implicated in MDSC recruitment. Mechanistically, inactivation of neddylation pathway inhibits activity of Cullin-RING ligase 1, a typical neddylation substrate, and induces accumulation of phosphorylated IκBα and subsequent blockage of NF-κB translocation, thus suppressing transcriptional activation of mCxcl5 or hCXCL6. Collectively, our data suggest that neddylation-NF-κB-mCXCL5 axis is involved in MDSC recruitment to the tumor sites and demonstrate that neddylation pathway is a good therapeutic target for patients with LUAD, particularly those receiving anti-MDSC therapy.
Plasma cell mastitis (PCM) and granulomatous mastitis (GM) are common inflammatory nonbacterial mastitis (NBM). However, the pathogenesis of NBM is still unclear.

In this study, we statistically analyzed the pathological features of PCM and GM using pathological HE staining and tissue transmission electron microscopy. The levels of MAC (C5b-9n), P-selectin, E-selectin, and ICAM-1 were detected through IHC, WB, ELISA, and qPCR. The expression level and location of MAC were observed by tissue immunological electron microscopy. In addition, exosomes were isolated from tissues, identified using transmission electron microscopy, and the densities were detected by Nano-FCM. Finally, the expression intensity of MAC in exosomes was detected by flow cytometry and immunoelectron microscopy.

The damage and apoptosis of mammary duct epithelial cells are the common pathological features of PCM and GM. MAC is primarily located in the cell membrane of mammary ductal epithelial cells and is significantly expressed in P role in the understanding of MAC. Furthermore, MAC is involved in inflammatory infiltration and lesion of mammary duct epithelial cells upregulated by P-selectin, E-selectin, and ICAM-1. These findings provide new insights into PCM and GM molecular mechanisms.
The pollen from Platanus acerifolia (P. acerifolia) is one of the main causes of allergic disorders. To date, only 4 allergens have been identified from this pollen. But previous studies showed that there still exist under-recognized allergens in it. The aim of this study was to comprehensively investigate the newly identified enolase (Pla a 6) as a novel allergen in the P. acerifolia pollen.

The natural (n) Pla a 6 was purified by combined chromatographic strategies. According to the identified internal peptides, the cDNA sequence encoding this allergen was matched from the mRNA-sequencing results of P. acerifolia pollen, which was further amplified and cloned. The recombinant (r) Pla a 6 was expressed and purified from E. coli. The allergenicity of this novel allergen was characterized by enzyme linked immunosorbent assay (ELISA), Western blot, inhibition ELISA, and basophil activation test (BAT).

A novel allergen from P. acerifolia pollen, named as Pla a 6 was thoroughly studied, which contained an otic and therapeutic approaches for P. acerifolia pollen allergy.mRNA vaccination is considered to be a promising strategy for tumor immunotherapy. Among, adequate antigen expression and regulation of tumor immune microenvironment are still the key to achieving therapeutic immounotherapy. In oreder to protect mRNA delivered to cells and reverse damaged dendritic cells(DCs), a novel vaccine delivery system composed of an α-Galactose ceramide/cationic liposome complex(α-GC-Lip) was constructed. The α-GC-liposome/protamine/mRNA vaccine complexes(α-GC-LPR) enabled the mRNA to be successfully translated into protein in the cytoplasm of antigen-presenting cells. Further, α-GC-LPR could stimulate dendritic cell maturation via significantly increasing the expression of bone marrow-derived cells(BMDCs) surface molecules and secretion of cytokines to improve the efficacy of immunotherapy. In vivo study, the α-GC-LPR was combined with programmed cell death protein 1(PD-1) inhibitor could activate natural killer cell(NK), T cells as well as significantly reduce the immunosuppression of immune cells, which induced strong antigen-specific immunity in breast cancer model. Our study indicated that the α-GC-LPR combined with immune checkpoint inhibitors as a potential design strategy to effectively enhance the antitumor immune response.Distracted driving is among the leading causes of roadway crashes worldwide. However, due to limitations of police-reported crash data, it is often challenging to understand the nature and magnitude of this problem. Distraction has also been shown to affect driver speed selection, which is important as both mean speed and speed variance have substantive impacts on crash risk. This study utilizes naturalistic driving data to investigate the relationship between the engagement in various secondary (non-driving) tasks and driver speed selection under different driving contexts. Separate analyses were conducted for low-speed and high-speed driving environments. Two-way random effects linear regression models were estimated for both speed regimes, while controlling for driver, roadway, and traffic characteristics. The differences were assessed based upon ten types of secondary tasks. In general, engagement in all tasks was found to decrease speeds in high-speed environments while the effects were mixed in low-speed settings.
