PM2.5 impairs macrophage functions to exacerbate pneumococcus-induced pulmonary pathogenesis
Particle and Fibre Toxicology, 2020 Background Pneumococcus is one of the most common human airway pathogens that causes life-threatening infections. Ambient fine particulate matter (PM) with aerodynamic diameter ≤ 2.5 μm (PM2.5) is known to significantly contribute to respiratory diseases.

Frontiers in Cell and Developmental Biology, 2020 Exposure to fine particulate matter (PM) with aerodynamic diameter ≤2.5 μm (PM2.5) is closely correlated with respiratory diseases. Microbiota plays a key role in maintaining body homeostasis including regulation of host immune status and metabolism.

Hepatitis B Virus, Pneumococcal, Diphtheria, and Tetanus Vaccination Responses in Compensated Cirrhosis. [PDF]
Liver IntABSTRACT Background and Aims Cirrhosis favours infections that can lead to liver decompensation and death. Some of these infections can be prevented by vaccination. This study aimed to evaluate the immune response after HBV, pneumococcal, diphtheria, and tetanus vaccination in cirrhotic patients.

Mechanisms and impact of genetic recombination in the evolution of Streptococcus pneumoniae
Computational and Structural Biotechnology Journal, 2015 Streptococcus pneumoniae (the pneumococcus) is a highly recombinogenic bacterium responsible for a high burden of human disease globally. Genetic recombination, a process in which exogenous DNA is acquired and incorporated into its genome, is a key ...

Influence of Obesity on Pneumococcus Infection Risk in the Elderly
Frontiers in Endocrinology, 2019 Obesity negatively affects immune function and host defense mechanisms. Obesity is associated with chronic activation of the innate immune system and consequent local and systemic inflammation which contribute to pathologic conditions such as type-2 ...
