Single‐Cell Insights Into Macrophage Subtypes in Pulmonary Infections

Advanced Science, EarlyView.
This review highlights the dynamic plasticity of macrophages during pulmonary infections and proposes an integrative framework defining six functional subtypes: Inflam‐Ms, Hub‐Ms, Reg‐Ms, Prolif‐Ms, Memory‐Ms, and Senesc‐Ms. Single‐cell omics delineate their distinct roles in homeostasis and infection, refining our understanding of macrophage ...

Deletions in the neuraminidase stalk region of H2N2 and H9N2 avian influenza virus subtypes do not affect postinfluenza secondary bacterial pneumonia [PDF]

, 2012
We investigated the synergism between influenza virus and Streptococcus pneumoniae, particularly the role of deletions in the stalk region of the neuraminidase (NA) of H2N2 and H9N2 avian influenza viruses.

Stromal Cell‐Mast Cell Communication Orchestrates Anti‐Viral Immunity in the Meninges

Advanced Science, EarlyView.
This study delineates the spatial distribution and postnatal maturation of meningeal mast cells and uncovers their essential role in antiviral immunity. Using genetic models, mast cells are shown to promote CD8⁺ T cell infiltration and viral clearance via IL‐33 receptor signaling and synergistic activation by IL‐33 and ATP from infected stromal cells ...

Contribution of Pili of S. Pneumoniae in the Onset of Meningitis

Folia Veterinaria, 2018
Bacterial meningitis is a devastating worldwide disease. Half of the survivors of meningitis remain with permanent neurological sequelae. The pathogenesis of meningitis is based on a complex host-pathogen interaction.

Prolonged Prophylactic Antibiotics Based on Preoperative Bile Culture Reduce Surgical Site Infections After Pancreaticoduodenectomy Following Preoperative Biliary Drainage: A Propensity‐Matched Analysis

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective The optimum duration of prophylactic antibiotics after pancreaticoduodenectomy following preoperative biliary drainage to prevent surgical site infections remains controversial. We evaluate whether a prolonged course of prophylactic antibiotics reduces surgical site infection after pancreaticoduodenectomy following biliary drainage ...

Clearance of mixed biofilms of Streptococcus pneumoniae and methicillin-susceptible/resistant Staphylococcus aureus by antioxidants N-acetyl-l-cysteine and cysteamine

Scientific Reports, 2022
Biofilm-associated infections are of great concern because they are associated with antibiotic resistance and immune evasion. Co-colonization by Staphylococcus aureus and Streptococcus pneumoniae is possible and a threat in clinical practice.
