Since 2022, cases of hepatitis of unknown origin have been reported in children worldwide. Adeno-associated virus type 2 (AAV2) was identified as a cause, with most affected children having the HLA-DRB1 04:01 genotype. In this study, we hypothesized that HLA-DRB1 04:01 in the host may also be a potential predisposing factor of acute hepatitis caused by other viruses.

Lung cancer remains a leading cause of cancer-related deaths worldwide, necessitating innovative treatments. Tumor-associated macrophages (TAMs) are primary immunosuppressive effectors that foster tumor proliferation, angiogenesis, metastasis, and resistance to therapy. They are broadly categorized into proinflammatory M1 and tumor-promoting M2 phenotypes, with elevated M2 infiltration correlating with poor prognosis.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease with high morbidity and mortality worldwide. Observational studies have shown correlations between common extrapulmonary comorbidities and COPD, but the existence of correlations does not necessarily prove a causal association. Therefore, causal relationships between diseases need to be explored by means of causal inference methods.

Background: Chronic obstructive pulmonary disease (COPD) has emerged as a very consequential issue threatening human life and health; therefore, research on its pathogenesis is urgently needed. A prior investigation discovered a significant elevation in the phosphoglycerate mutase 5 (PGAM5) expression in the lung tissue of COPD smoking patients. This rise in expression is closely associated with COPD severity.

LSerine, a non-essential amino acid (NEAA), can be obtained through diet or synthesis. Functionally, L-serine not only serves as the precursor of other amino acids, lipids, and nucleotides, but also participates in the folate/methionine cycle. An increasing number of studies have demonstrated that L-serine is widely used in the adjuvant therapy of many diseases (e.
