Novel therapies are crucial for drug-resistant tuberculosis (TB). Host-directed adjunct therapies offer a promising strategy to shorten treatment duration and combat resistant Mycobacterium tuberculosis (Mtb) strains.
Area of Science:
- Microbiology
- Immunology
- Pharmacology
Background:
- Drug-resistant tuberculosis (TB) presents a critical unmet need for novel, safe, and shorter treatment regimens.
- Current TB drug discovery often targets essential Mycobacterium tuberculosis (Mtb) genes, necessitating new strategies like host-directed therapies.
- Adjunct therapies targeting host pathways or nonmicrobicidal proteins offer a paradigm shift, potentially reducing treatment duration and overcoming resistance.
Purpose of the Study:
- To discuss novel strategies for treating drug-resistant tuberculosis (TB).
- To explore the potential of host-directed and nonmicrobicidal adjunct therapies.
- To highlight recent advances and challenges in developing new TB treatments.
Main Methods:
- Review of recent advances in targeting host-pathogen interactions.
- Identification of host pathways implicated in TB, such as eicosanoid regulation and angiogenesis.
- Exploration of drug repurposing for TB treatment, including metformin and verapamil.
Main Results:
- Host-directed adjunct therapies show potential for shorter TB treatment durations due to novel mechanisms and reduced resistance.
- Pathways like eicosanoid regulation and angiogenesis are implicated in host-pathogen interactions relevant to TB.
- Existing drugs like metformin and verapamil are identified as candidates for TB treatment repurposing.
Conclusions:
- Host-directed and pathogen-directed adjunct therapies are essential for a paradigm shift in TB treatment.
- Targeting host pathways and nonmicrobicidal proteins offers a viable strategy to overcome drug resistance and shorten treatment.
- Further research into these adjunct therapies and drug repurposing holds significant promise for combating TB.
