Exploiting autophagy-targeting natural compounds for potential antimicrobial actions

Area of Science:

• Cellular Biology
• Microbiology
• Pharmacology

Background:

• Natural products are key therapeutic agents, especially for infectious diseases.
• Autophagy, an intracellular degradation pathway, plays a vital role in host defense against various pathogens.
• Modulation of autophagy by natural products presents a promising host-directed therapy strategy.

Purpose of the Study:

• To review the current understanding of natural products' antimicrobial actions via autophagy regulation.
• To explore the roles of different natural product classes in modulating autophagy for infectious disease control.
• To discuss the potential of natural product-autophagy interactions as novel antimicrobial treatments.

Main Methods:

• Literature review of studies investigating natural products and autophagy in the context of infectious diseases.
• Analysis of distinct natural product classes (polyphenols, alkaloids, terpenoids, etc.) and their autophagy-modulating mechanisms.
• Examination of signaling pathways and molecular interplay between natural products, autophagy, and pathogen response.

Main Results:

• Numerous natural products can activate or inhibit autophagy, thereby enhancing antimicrobial responses.
• Specific classes of natural products, including polyphenols and alkaloids, demonstrate significant autophagy modulation capabilities.
• The precise mechanisms by which natural products affect autophagy (direct vs. indirect) and their impact on host-pathogen interactions require further elucidation.

Conclusions:

• Natural products offer a versatile platform for developing autophagy-based host-directed antimicrobial therapies.
• Understanding the intricate molecular mechanisms can lead to innovative strategies to combat infectious diseases and drug resistance.
• Further research is needed to clarify the direct vs. indirect effects and potential pathogen evasion strategies related to autophagy modulation.
