Targeting apoptosis pathways in infections.

Area of Science:

• Molecular Biology
• Immunology
• Pathogen-Host Interactions

Background:

• Apoptosis, or programmed cell death, is crucial for mammalian development and immunity, eliminating harmful cells.
• Apoptosis plays a key role in the cellular immune response by clearing intracellular pathogens and resolving infections.
• Pathogens have developed diverse strategies to evade or subvert apoptosis to ensure their survival.

Purpose of the Study:

• To review host-pathogen interactions that specifically impact apoptotic pathways.
• To discuss how pathogens control host cell fate and influence infection outcomes.
• To explore the therapeutic potential of targeting host death pathways in infectious diseases.

Main Methods:

• Literature review focusing on selected host-pathogen interactions affecting apoptosis.
• Analysis of pathogen effector molecules that induce or inhibit apoptosis.
• Discussion of therapeutic strategies targeting host death factors.

Main Results:

• Pathogens can either subvert apoptosis to survive or induce it in host cells.
• Pathogen manipulation of host cell death pathways significantly determines infection outcomes.
• Small molecule inhibitors that induce apoptosis in cancer cells show potential for treating infected cells.

Conclusions:

• Understanding how pathogens interact with apoptosis is key to controlling infections.
• Targeting host death factors represents a promising therapeutic avenue for treating infectious diseases.
