Article Synopsis
  • The study investigates mutations in the SARS-CoV-2 Omicron variant, highlighting how natural selection has allowed beneficial changes in the virus to thrive and spread globally.
  • By analyzing over 496,000 Omicron sequences, researchers identified significant mutations in the Spike (S) protein that enhance the virus's ability to infect hosts and evade immune responses.
  • One key finding is the P1263L substitution in the Spike protein that increases viral entry and boosts the efficacy of mRNA vaccines, providing insights for vaccine optimization against COVID-19.

Article Synopsis
  • Immune checkpoint blockade (ICB) can induce tumor ferroptosis, but many patients don't respond because tumors evade this process within the tumor microenvironment (TME).
  • Researchers found that SLC13A3 acts as a transporter for itaconate in tumor cells, contributing to resistance against ferroptosis, which weakens tumor immunity and reduces ICB effectiveness.
  • Targeting SLC13A3 through various methods, like genetic alteration or using a specific inhibitor, can sensitize tumors to ferroptosis, slow down tumor growth, and enhance the effectiveness of ICB treatments, highlighting SLC13A3 as a potential target for cancer therapy.

Article Synopsis
  • The study investigates how the compound probiotic VSL#3 affects the metabolism of various cytochrome P450 enzyme probe drugs in male Wistar rats.
  • Results show that VSL#3 alters the gut microbiota, leading to significant increases in the bioavailability of certain drugs, like omeprazole, while decreasing the bioavailability of others like tolbutamide and chlorpropamide.
  • Additionally, the administration of VSL#3 impacted gene expression related to drug metabolism and intestinal structure, suggesting that probiotics can influence how drugs are processed in the body.

Background: Apelin is an endogenous prepropeptide that regulates cardiac homeostasis and various physiological processes. Intravenous injection has been shown to improve cardiac contractility in patients with heart failure. However, its short half-life prevents studying its impact on left ventricular remodeling in the long term.

Hyperproliferative keratinocytes and subcutaneous inflammation contribute to the characteristic symptoms of psoriasis, including erythema, scales, or scaly plaques on the skin. These symptoms significantly affect patients' quality of life and cause severe physical and psychological distress. However, current treatment strategies have limited therapeutic effect and may lead to adverse side effects.

Immune tolerance mechanisms are shared in cancer and pregnancy. Through cross-analyzing single-cell RNA-sequencing data from multiple human cancer types and the maternal-fetal interface, we found B7-H4 (VTCN1) is an onco-fetal immune tolerance checkpoint. We showed that genetic deficiency of B7-H4 resulted in immune activation and fetal resorption in allogeneic pregnancy models.

Recent single-arm studies involving neoadjuvant camrelizumab, a PD-1 inhibitor, plus chemotherapy for resectable locally advanced esophageal squamous cell carcinoma (LA-ESCC) have shown promising results. This multicenter, randomized, open-label phase 3 trial aimed to further assess the efficacy and safety of neoadjuvant camrelizumab plus chemotherapy followed by adjuvant camrelizumab, compared to neoadjuvant chemotherapy alone. A total of 391 patients with resectable thoracic LA-ESCC (T1b-3N1-3M0 or T3N0M0) were stratified by clinical stage (I/II, III or IVA) and randomized in a 1:1:1 ratio to undergo two cycles of neoadjuvant therapy.

Article Synopsis
  • The study evaluates the effectiveness of neoadjuvant immunotherapy combined with chemotherapy in patients with localized EGFR-mutant non-small cell lung cancer (NSCLC) through a phase 2 trial involving 18 participants.
  • Interim results show that while many patients had positive radiological responses, only 44% reached major pathological response, and there were no cases of complete response.
  • The research indicates that certain T cell populations are linked to resistance against immunotherapy and suggests that monitoring circulating tumor DNA (ctDNA) could help identify patients less likely to respond to such treatments.

Tumor-associated macrophages (TAMs) shape tumor immunity and therapeutic efficacy. However, it is poorly understood whether and how post-translational modifications (PTMs) intrinsically affect the phenotype and function of TAMs. Here, we reveal that peptidylarginine deiminase 4 (PAD4) exhibits the highest expression among common PTM enzymes in TAMs and negatively correlates with the clinical response to immune checkpoint blockade.

Article Synopsis
  • A study was conducted to understand how genetic factors and clinical features affect pregnancy outcomes in Chinese women with chronic pancreatitis (CP), focusing on specific gene mutations (SPINK1, PRSS1, CTRC, CFTR).
  • Out of 160 female CP patients, 59.4% had pathogenic gene mutations, showing that those with mutations experienced higher rates of adverse pregnancy outcomes such as preterm delivery and abortion compared to those without mutations.
  • The research concluded that mutations in CP-susceptibility genes, particularly in SPINK1, are significant risk factors for adverse pregnancy outcomes, highlighting the need for careful monitoring of affected patients during pregnancy.

Biological nutrient removal processes involving the use of activated sludge (AS) to treat municipal wastewater normally result in high aeration energy consumption and significant greenhouse gas (GHG) emissions. Therefore, developing cost-efficient and environmentally friendly processes for wastewater treatment is vital. In this work, a novel non-aerated microalgal-bacterial membrane photobioreactor (MB-MPBR) was proposed, and its feasibility for organic contaminant and nutrient removals was evaluated, for the first time.

This prospective multicenter phase II study evaluated the clinical efficacy of neoadjuvant nivolumab-exclusive (N) and nivolumab-chemotherapy (N/C) combinations based on PD-L1 expression. Eligible patients exhibited resectable clinical stage IIA-IIIB (AJCC 8th edition) NSCLC without EGFR/ALK alterations. Patients received either mono-nivolumab (N) or nivolumab + nab-paclitaxel+ carboplatin (N/C) for three cycles based on PD-L1 expression.

Background: Lymphatic vessels are responsible for tissue drainage, and their malfunction is associated with chronic diseases. Lymph uptake occurs via specialized open cell-cell junctions between capillary lymphatic endothelial cells (LECs), whereas closed junctions in collecting LECs prevent lymph leakage. LEC junctions are known to dynamically remodel in development and disease, but how lymphatic permeability is regulated remains poorly understood.

Immune checkpoint inhibitors (ICIs) use antibodies that block cell surface immune checkpoint proteins with great efficacy in treating immunogenic or "immune hot" tumors such as melanoma, kidney, and lung adenocarcinoma. ICIs have limited response rates to other non-immunogenic cancers. The tumor microenvironment (TME) consists of many cell types that collectively promote tumor progression.

Background: Recent evidence indicates that long-term visit-to-visit blood pressure variability (BPV) may be associated with risk of cardiovascular disease. We, therefore, aimed to determine the potential associations of long-term BPV from childhood to middle age with subclinical kidney damage (SKD) and albuminuria in adulthood.

Methods: Using data from the ongoing cohort of Hanzhong Adolescent Hypertension study, which recruited children and adolescents aged 6 to 18 years at baseline, we assessed BPV by SD and average real variability (ARV) for 30 years (6 visits).

This randomized, open-label, multi-center phase 2 study (NCT03116152) assessed sintilimab, a PD-1 inhibitor, versus chemotherapy in patients with esophageal squamous cell carcinoma after first-line chemotherapy. The primary endpoint was overall survival (OS), while exploratory endpoint was the association of biomarkers with efficacy. The median OS in the sintilimab group was significantly improved compared with the chemotherapy group (median OS 7.

Although human antibodies elicited by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid (N) protein are profoundly boosted upon infection, little is known about the function of N-reactive antibodies. Herein, we isolate and profile a panel of 32 N protein-specific monoclonal antibodies (mAbs) from a quick recovery coronavirus disease-19 (COVID-19) convalescent patient who has dominant antibody responses to the SARS-CoV-2 N protein rather than to the SARS-CoV-2 spike (S) protein. The complex structure of the N protein RNA binding domain with the highest binding affinity mAb (nCoV396) reveals changes in the epitopes and antigen's allosteric regulation.
