Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Modified-Release Drug Delivery Systems: Site-Targeted01:24

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

Area of Science:

  • Neurosurgery
  • Neurology
  • Psychiatry

Background:

  • Deep brain stimulation (DBS) has expanded from ablative neurosurgery targets like the VIM thalamus for tremor.
  • Early applications included pallidum for Parkinson's disease (PD) tremor and dyskinesias, and internal capsule for obsessive-compulsive disorder (OCD).
  • Advances in basic research enabled new DBS targets due to its favorable characteristics (low morbidity, reversibility, adaptability).

Purpose of the Study:

  • To explore the extension of DBS to novel targets based on evolving scientific understanding.
  • To investigate the efficacy of DBS for a wider range of neurological and psychiatric disorders.
  • To highlight serendipitous findings and potential new therapeutic avenues.

Main Methods:

  • Extension of high-frequency DBS techniques to established ablative neurosurgery targets.
  • Application of DBS to targets identified through basic research, such as the subthalamic nucleus (STN) and pedunculopontine nucleus (PPN).
  • Exploration of basal ganglia and limbic system targets for psychiatric and cognitive disorders.

Main Results:

  • STN DBS effectively treats the motor symptoms of Parkinson's disease.
  • PPN DBS shows promise for gait disorders in PD.
  • New targets like the subgenual cortex (CG 25) and accumbens nucleus are explored for depression, addiction, and anorexia nervosa.
  • Thalamic intralaminar nuclei are investigated for minimally conscious states.
  • Unexpected effects, such as STN in OCD and limbic effects from VMH stimulation, suggest potential for treating cognitive impairment and memory deficits.

Conclusions:

  • DBS has a continually expanding therapeutic scope, driven by both scientific research and serendipitous discoveries.
  • Novel targets in the basal ganglia and limbic system offer new treatment possibilities for complex psychiatric and cognitive conditions.
  • Ethical considerations are paramount as DBS applications broaden.
