Identifying new drug targets is challenging. This study proposes a functional approach by examining host-pathogen interactions to find novel therapeutic targets, aiming to overcome drug resistance.
Area of Science:
- Molecular Biology
- Pharmacology
- Immunology
Background:
- Drug development has evolved from traditional herbal remedies to sophisticated scientific methods.
- Defining effective drug targets remains a significant challenge in modern drug discovery.
- Classical and high-throughput screening methods face limitations, including the emergence of drug resistance.
Purpose of the Study:
- To propose a novel functional approach for identifying drug targets by studying host-pathogen interactions.
- To investigate alterations in host immune responses, gene expression, and cell signaling during infection.
- To identify pro-parasitic gene products and kinases as potential therapeutic targets.
Main Methods:
- Studying host-pathogen interactions to analyze immune response modifications.
- Profiling host gene expression and cell signaling molecule activation, particularly kinases.
- Demonstrating the efficacy of reversing identified gene expression and protein activation profiles.
Main Results:
- Host-pathogen interactions induce specific gene expression and protein activation patterns necessary for pathogen survival.
- Reversing these induced profiles effectively ameliorates infection.
- Identified pro-parasitic gene products and kinases are validated as potential drug targets.
Conclusions:
- A functional approach focusing on host-pathogen interactions offers a promising strategy for novel drug target identification.
- Targeting host factors manipulated by pathogens can overcome limitations of traditional drug discovery, including resistance.
- This approach facilitates the development of more effective therapeutics against infectious diseases.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Structure-Activity Relationships and Drug Design
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence its...
Principles of Drug Action
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
Protein Networks
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
