Targeted Cancer Therapies

7.4K
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.
There are several types of targeted therapies against...

Cell-surface Signaling01:21

Cell-surface Signaling

51.3K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

Background:

  • Cell membrane nanoparticles (CNPs) are emerging as advanced drug delivery vehicles.
  • Their biological origin provides unique surface proteins and glycans for enhanced functionality.
  • CNPs overcome limitations of traditional nanoparticles, such as protein corona formation and immune evasion.

Purpose of the Study:

  • This review examines the applications of CNPs in cancer therapeutics.
  • It explores the structural evolution and surface engineering of CNPs.
  • The review aims to assess the future prospects of CNPs in clinical trials.

Main Methods:

  • Review of existing literature on cell membrane nanoparticle research.
  • Analysis of studies focusing on CNP structural evolution and surface engineering.
  • Investigation of CNPs leveraging inherent cell membrane functionalities and engineered modifications.

Main Results:

  • CNPs demonstrate prolonged blood circulation due to inhibited protein corona and suppressed macrophage phagocytosis.
  • Homotypic targeting of CNPs to their cells of origin reduces side effects.
  • Minimized nonspecific immune activation due to their non-xenobiotic nature.

Conclusions:

  • CNPs represent a promising platform for cancer therapy with enhanced efficacy and safety.
  • Continued research in genetic and chemical engineering will further functionalize CNPs.
  • CNPs show significant potential for future clinical translation in oncology.
