Cell death and autophagy in tuberculosis.

Area of Science:

• Immunology
• Cell Biology
• Infectious Diseases

Background:

• Mycobacterium tuberculosis infects one-third of the global population by evading innate and adaptive immunity.
• The bacterium is a facultative intracellular parasite, exploiting mononuclear phagocytes for survival and replication.
• Host-pathogen interactions dictate pathogen fate, host cell survival, and the outcome of cell death.

Purpose of the Study:

• To review the roles of cell death and autophagy in tuberculosis (TB) pathogenesis.
• To explore how these cellular processes influence TB disease progression.
• To identify potential therapeutic targets within these pathways for TB treatment and prevention.

Main Methods:

• Literature review and synthesis of existing research on cell death and autophagy in TB.
• Analysis of pathogen-host interactions within mononuclear phagocytes.
• Discussion of the implications of cell death and autophagy for disease outcome.

Main Results:

• Cell death and autophagy are critical determinants in TB pathogenesis.
• The timing and mode of host cell death can favor either the host or the pathogen.
• Autophagy modulation can impact pathogen control and host cell survival.

Conclusions:

• Cell death and autophagy are fundamental to understanding TB pathogenesis.
• Targeting these cellular processes presents a promising strategy for novel TB treatments and prevention.
• Further research into host-directed therapies focusing on cell death and autophagy is warranted.
