Mycobacterial infections, caused by various species within the Mycobacterium genus, remain one of the main challenges to global health across the world. Understanding the complex interplay between the host and mycobacterial pathogens is essential for developing effective diagnostic and therapeutic strategies. Host long noncoding RNAs (lncRNAs) have emerged as key regulators in cellular response to bacterial infections within host cells.

Article Synopsis
  • Extracellular vesicles (EVs), like exosomes, are important for how cells communicate and control processes in other cells.
  • The study focused on Mycobacterium abscessus, a non-tuberculous bacterium that can lead to serious lung infections, particularly in individuals with pre-existing lung issues.
  • Researchers found that infection with M. abscessus increased the release of specific exosomes from mouse macrophages, which affected protein content and promoted bacterial growth while lowering glutamine levels, suggesting that these exosomes hinder macrophage ability to kill the bacteria by eliminating glutamine.

Nontuberculous Mycobacteria (NTM) are a group of emerging bacterial pathogens that have been identified in cystic fibrosis (CF) patients with microbial lung infections. The treatment of NTM infection in CF patients is challenging due to the natural resistance of NTM species to many antibiotics. Mycobacterium abscessus is one of the most common NTM species found in the airways of CF patients.

Aging has a significant impact on the immune system, leading to a gradual decline in immune function and changes in the body's ability to respond to bacterial infections. Non-tuberculous mycobacteria (NTM), also known as atypical mycobacteria or environmental mycobacteria, are commonly found in soil, water, and various environmental sources. While many NTM species are considered opportunistic pathogens, some can cause significant infections, particularly in individuals with compromised immune systems, such as older individuals.
