Cases of laboratory-confirmed SARS-CoV-2 reinfection have been reported in a number countries. Further, the level natural immunity induced by infection is not fully clear, nor it clear if primary protective against reinfection. To investigate potential association between serum antibody titres and SARS-CoV-2, ferrets with different levels NAb after were subjected to heterologous strain. All reinfected showed active virus replication upper respiratory gastro-intestinal tracts. However, high...

While the seroprevalence of SARS-CoV-2 in healthy people does not differ significantly among age groups, those aged 65 years or older exhibit strikingly higher COVID-19 mortality compared to younger individuals. To further understand differing manifestations patients different ages, three groups ferrets are infected with SARS-CoV-2. Although is isolated from all regardless age, (≥3 old) show viral loads, longer nasal virus shedding, and more severe lung inflammatory cell infiltration,...

Abstract RIPK3–ZBP1–MLKL-mediated necroptosis is a proinflammatory cell death process that crucial for antiviral host defence. RIPK3 self-oligomerization and autophosphorylation are prerequisites executing necroptosis, yet the underlying mechanism of virus-induced activation remains elusive. Interferon-inducible 2′-5′ oligoadenylate synthetase-like (OASL) protein devoid enzymatic function but displays potent activity. Here we describe role OASL as promoter scaffolds RIPK3–ZBP1 non-canonical...

Thioredoxin-interacting protein (TXNIP) has emerged as a key player in cancer and diabetes since it targets thioredoxin (TRX)-mediated redox regulation glucose transporter (GLUT)-mediated metabolism. TXNIP consists of two arrestin (ARR, N-ARR C-ARR) domains at its amino-terminus PPxY (PY) motifs di-leucine (LL) motif for endocytosis carboxyl-terminus. Here, we report that shuffles between TRX GLUTs to regulate homeostasis intracellular oxidative stress While functions gatekeeper by default,...

One of the hallmarks latent phase Kaposi's sarcoma-associated herpesvirus (KSHV) infection is global repression lytic viral gene expression. Following de novo KSHV infection, establishment latency involves chromatinization incoming genomes and recruitment host Polycomb repressive complexes (PRC1 PRC2) to promoters genes, which accompanied by inhibition genes. However, mechanism how PRCs are recruited episome still unknown. Utilizing a genetic screen genes in context genome, we identified...

Abstract To gain insight into regulatory mechanisms of tissue‐specific Corazonin ( Crz ) gene expression and its functions in Drosophila , we cloned the genes from four species D. melanogaster, simulans, erecta virilis performed comparative analyses sequences patterns using situ hybridization immunohistochemistry. Although showed a great deal diversity, CNS were highly conserved examined here. In melanogaster larva, was found pairs neurons per cerebral lobe eight bilateral ventral nerve...

Significance While understanding metabolic change of tumor cells is crucial to improve cancer therapy, current 2D cell culture condition may not fully recapitulate in vivo environment tumors. Our metabolomics analysis demonstrates that proline metabolism critical for the KSHV-transformed growth 3D culture, culture. Specifically, KSHV K1 oncoprotein activates PYCR biosynthesis enzyme, increasing intracellular concentration vitro spheroid and tumorigenesis. This study describes an oncogenic...

ABSTRACT Kaposi's sarcoma‐associated herpesvirus (KSHV) employs diverse mechanisms to subvert host immune responses, contributing its infection and pathogenicity. As an evasion strategy, KSHV encodes the Membrane‐Associated RING‐CH (MARCH)‐family E3 ligases, K3, K5, which target remove several regulators from cell surface. In this study, we investigate impact of K3 K5 on lymphotoxin receptor (LTβR) ligands, LTβ LIGHT, are type II transmembrane proteins function as pivotal mediators during...

Abstract Lung mast cells are important in host defense, and excessive proliferation or activation of these can cause chronic inflammatory disorders like asthma. Two parallel pathways induced by KIT–stem cell factor (SCF) FcεRI–immunoglobulin E interactions critical for the cells, respectively. Here, we report that cell-expressed membrane protein1 (MCEMP1), a lung-specific surface protein, functions as an adaptor KIT, which promotes SCF-mediated proliferation. MCEMP1 elicits intracellular...

Patients with immune-mediated inflammatory diseases (IMIDs) like rheumatoid arthritis (RA) are at higher risk for severe COVID-19 and long-term complications in bone health. Emerging clinical evidence demonstrated that SARS-CoV-2 infection reduces turnover promotes loss, but the mechanism underlying worsened health remains elusive. This study sought to identify specific immune mediators exacerbated preexisting IMIDs after exposure. Plasma samples from 4 groups were analyzed: healthy, IMID...
