Host‐directed therapy to combat mycobacterial infections*

Gül Kilinç, Anno Saris, Tom H. M. Ottenhoff, Mariëlle C. Haks

Immunological Reviews > 301 > 1 > 62 - 83

Upon infection, mycobacteria, such as Mycobacterium tuberculosis (Mtb) and nontuberculous mycobacteria (NTM), are recognized by host innate immune cells, triggering a series of intracellular processes that promote mycobacterial killing. Mycobacteria, however, have developed multiple counter‐strategies to persist and survive inside host cells. By manipulating host effector mechanisms, including phagosome...

Timothy J Ford, Robyn A Silcock, Steven M Holland

Journal of Paediatrics and Child Health > 57 > 1 > 15 - 18

Nontuberculous mycobacteria (NTM) are ubiquitous organisms in our surrounding environment. Four distinct clinical syndromes associated with NTM infection have been described: skin and soft tissue disease, lymphadenitis, disseminated disease and pulmonary disease. In children, lymphadenitis is the most common NTM clinical entity, particularly affecting those aged 1–5 years who have no known risk factors...
