Tuberculosis (TB) remains a significant global health challenge, ranking among the top ten causes of death worldwide. Despite ongoing efforts, over a million people die from TB each year. Traditional treatment involves a lengthy regimen of antibiotics, but this approach has its drawbacks. Issues such as poor success rates, the rise of drug-resistant strains, and low adherence to treatment highlight the need for alternative strategies. Moreover, the complexity of TB’s interaction with other diseases, such as HIV and diabetes, necessitates more nuanced treatment approaches.

Emergence of Host-Directed Therapies (HDTs)

Host-directed therapies (HDTs) have become a viable substitute in this regard. HDTs alter the host’s immune response to strengthen the body’s defences against tuberculosis (TB), in contrast to traditional antibiotics that directly target the pathogen. This strategy is predicated on an understanding of the immune system’s interaction with Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB). Researchers have discovered critical host pathways essential to developing and resolving tuberculosis, including autophagy, inflammation, and immune regulation.

How HDTs Work

HDTs aim to enhance the host’s immune response to achieve several goals:

• Promote Pathogen Clearance: By boosting the host’s immune system, HDTs can help the body clear the TB bacteria more effectively.
• Reduce Tissue Damage: HDTs can help modulate the immune response to reduce the damage caused by inflammation in the tissues affected by TB.
• Overcome Drug Resistance: By focusing on the host’s immune system, HDTs may offer new ways to combat drug-resistant strains of TB.
• Evaluating Efficacy and Safety: Both preclinical and clinical studies are essential to assess the safety and effectiveness of HDT candidates. These studies help determine how well these therapies work and their potential side effects.

Encourage cooperation and creativity

The field of HDT research is dynamic and fast-developing. By encouraging cross-disciplinary collaboration, researchers can improve our knowledge of host-pathogen interactions and create novel host-targeted interventions. Original Articles, Reviews, Methodologies, Perspectives, and Case Reports are welcome submission forms. By working together, we can advance TB treatment and get one step closer to finding better ways to handle this global health emergency.

Key Takeaways

Host-directed therapies (HDTs) represent a promising shift in the fight against tuberculosis. They focus on enhancing the host’s ability to combat the disease. As research progresses, HDTs may become a vital component of a comprehensive approach to TB management, addressing both drug-resistant strains and co-morbid conditions.
