Autophagy is an evolutionarily conserved cellular recycling mechanism that occurs at a basal level in all cells. It can be further induced by various stimuli including starvation, hypoxia, and treatment with cytokines such as IFNG/IFNγ TGFB/TGFβ. Type I IFNs are proteins induce antiviral state They also have antiproliferative, proapoptotic immunomodulatory activities. We investigated whether type IFN autophagy multiple human cell lines. found IFNA2c/IFNα2c IFNB/IFNβ induces 24 h Daudi B...
Immune checkpoint inhibitors (ICIs) have caused revolutionary changes in cancer treatment, but low response rates remain a challenge. Semaphorin 4A (Sema4A) modulates the immune system through multiple mechanisms mice, although role of human Sema4A tumor microenvironment remains unclear. This study demonstrates that histologically Sema4A-positive non–small cell lung (NSCLC) responded significantly better to anti–programmed death 1 (PD-1) antibody than Sema4A-negative NSCLC. Intriguingly,...

We confirmed EA-specific via validation in 61 BA 23 controls. To further validate these findings, we 6 chronic rhinosinusitis...
Abstract Chronic obstructive pulmonary disease (COPD) has been recently characterized as a of accelerated lung aging, but the mechanism remains unclear. Tetraspanins have emerged key players in malignancy and inflammatory diseases. Here, we found that CD9/CD81 double knockout (DKO) mice with COPD-like phenotype progressively developed syndrome resembling human including cataracts, hair loss, atrophy various organs, thymus, muscle, testis, resulting shorter survival than wild-type (WT) mice....
Nontuberculous mycobacterial pulmonary disease (NTM-PD), mainly caused by Mycobacterium avium complex (MAC), and tuberculosis (TB) are emerging health problems worldwide. However, because their clinical features often similar, it remains difficult to differentiate NTM-PD from TB when the diagnosis cannot be made sputum culture. To investigate potential serum biomarkers, we conducted non-targeted proteome analysis on extracellular vesicles (EVs) collected 10 patients with MAC (MAC-PD), 7 TB,...
Although responses to EGFR tyrosine kinase inhibitors (EGFR-TKIs) are initially positive, 30%-40% of patients with EGFR-mutant tumors do not respond well EGFR-TKIs, and most lung cancer harboring mutations experience relapse resistance. Therefore, it is necessary identify only the mechanisms underlying EGFR-TKI resistance, but also potentially novel therapeutic targets and/or predictive biomarkers for adenocarcinoma. We found that GPI-anchored protein semaphorin 7A (SEMA7A) highly induced by...
Abstract Background Cytosine-phosphate-guanine oligodeoxynucleotide (CpG ODN) (K3)—a novel synthetic single-stranded DNA immune adjuvant for cancer immunotherapy—induces a potential Th1-type response against cells. We conducted phase I study of CpG ODN (K3) in patients with lung to assess its safety and patients’ responses. Methods The primary endpoint was the proportion dose-limiting toxicities (DLTs) at each dose level. Secondary endpoints included profile, an response, including dynamic...
The methyltransferase-like 3 (METTL3)-/METTL14-containing complex predominantly catalyzes N6-methyladenosine (m6A) modification, which affects mRNA stability. Although the METTL14 R298P mutation is found in multiple cancer types, its biological effects are not completely understood. Here, we show that heterozygous promotes cell proliferation, whereas homozygous reduces proliferation. Methylated RNA immunoprecipitation sequencing analysis indicates m6A modification at canonical motifs....
Calcium-dependent activator protein for secretion 1 (CAPS1) plays a distinct role in the priming step of dense core vesicle (DCV) exocytosis. CAPS1 pre-mRNA is known to undergo adenosine-to-inosine RNA editing its coding region, which results glutamate-to-glycine conversion at site C-terminal region. However, physiological significance remains elusive. Here, we created mutant mice edited was solely expressed. These were lean due increased energy expenditure caused by physical hyperactivity....
Messenger RNA (mRNA) vaccines that protect against COVID-19 are widely used in many countries owing to their high efficacy and safety profiles. Recently, few severe adverse events, such as anaphylaxis myocarditis, were reported healthy individuals. The of mRNA has not been adequately studied patients with interstitial lung disease. We report 2 cases acute exacerbation preexisting pneumonia associated vaccination. In both cases, disease was stable before the Initial responses steroid therapy...
Progressive pulmonary fibrosis (PPF), defined as the worsening of various interstitial lung diseases (ILDs), currently lacks useful biomarkers. To identify novel biomarkers for early detection patients at risk PPF, we performed a proteomic analysis serum extracellular vesicles (EVs). Notably, identified candidate were enriched lung-derived proteins participating in fibrosis-related pathways. Among them, surfactant-associated protein B (SFTPB) EVs could predict ILD progression better than...
The present study investigates the expression of VLA-4 on thymocytes at various stages maturation and their capacity to adhere thymic stromal cells. Whole were stained with anti-CD4 anti-CD8, as well anti-VLA-4 antibodies. Flow microfluorometric analyses revealed that a) most CD4-8- (double negative DN) CD4-8intermediate thymocyte populations expressed large amounts VLA-4, b) levels considerably markedly reduced CD4+8+ positive DP) single (SP) (CD4+8- or CD4-8+) populations, respectively....
Abstract Thymic shared antigen-1 (TSA-1) is a glycosyl-phosphatidylinositol (GPI)-anchored differentiation Ag expressed on murine lymphocytes, and identical to stem cell Ag-2 (Sca-2). Using newly established mAb against TSA-1/Sca-2, we have previously shown that surface TSA-1 expression induced upon activation in T cells, anti-TSA-1 inhibits IL-2 production by anti-CD3 stimulation hybridomas. In the present study, analyzed functional role of during using normal hybridomas, transfected Jurkat...

Abstract Coronavirus disease 2019 (COVID‐19) can cause severe lymphopenia and respiratory failure requiring prolonged invasive mechanical ventilation (MV). COVID‐19 patients with or are at risk of developing secondary infections. Here, we present the needle autopsy findings a critically ill patient who required reintubation MV, eventually died cytomegalovirus (CMV) pneumonia. This case highlights potential long‐term steroid use need for routine monitoring CMV infection in COVID‐19.
Abstract Cancer immunotherapy has shown great promise as a new standard therapeutic strategy against cancer. However, the response rate and survival benefit remain unsatisfactory because most current approaches, such use of immune checkpoint inhibitors, depend on spontaneous antitumor responses. One possibility for improving efficacy is to promote immunity using adjuvants or specific cytokines actively. IL-33 been candidate cytokine therapies, but it remains unclear how in which situations...
Abstract Small-cell lung cancer (SCLC) easily recurs with a multidrug resistant phenotype. However, standard therapeutic strategies for relapsed SCLC remain unestablished. We found that human epidermal growth factor receptor 2 (HER2) is not only expressed in pretreated specimens, but also upregulated when HER2-positive cells acquire chemoresistance. Trastuzumab induced differential levels of antibody-dependent cell-mediated cytotoxicity (ADCC) to cells. Furthermore, as mechanism the ADCC, we...
