Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.

Introduction: Torque Teno Virus (TTV), an "orphan" virus with unclear pathology, has been associated with various diseases and immune dysfunctions. This study investigates the link between TTV viremia and clinical markers in patients with severe to very severe COPD undergoing respiratory rehabilitation.
Methods: We analyzed 102 elderly COPD patients, stratified by TTV viremia levels (< or ≥ 4 log10 copies/mL).

Evidence suggests that bats are important hosts of filoviruses, yet the specific species involved remain largely unidentified. Niemann-Pick C1 (NPC1) is an essential entry receptor, with amino acid variations influencing viral susceptibility and species-specific tropism. Herein, we conducted combinatorial binding studies with seven filovirus glycoproteins (GPs) and NPC1 orthologs from 81 bat species.

Functional regeneration of the lung's gas exchange surface following injury requires the coordination of a complex series of cell behaviors within the alveolar niche. Using single-cell transcriptomics combined with lineage tracing of proliferating progenitors, we examined mouse lung regeneration after influenza injury, demonstrating an asynchronously phased response across different cellular compartments. This longitudinal atlas of injury responses has produced a catalog of transient and persistent transcriptional alterations in cells as they transit across axes of differentiation.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral hemorrhagic fever with a high fatality rate and notable public health impact, caused by a novel phlebovirus, primarily transmitted through infected tick bites. This study aimed to assess the prevalence of co-infections among hospitalized patients with SFTS, characterize isolated pathogens, and evaluate demographics, clinical features, and laboratory variations to identify potential risk factors for co-infections. In a cohort of 78 SFTS patients categorized into co-infection and non-co-infection groups, 44.
