Insights

Macropinocytosis, a cellular uptake process, offers a promising route for delivering larger drug quantities. This review explores its potential for targeted intracellular drug delivery systems.

Area of Science:

  • Cell Biology
  • Biotechnology
  • Pharmacology

Background:

  • Macropinocytosis is an evolutionarily conserved endocytic process in eukaryotic cells.
  • It facilitates the internalization of large fluid volumes, making it suitable for drug delivery.
  • Macropinocytosis plays roles in both healthy and pathological cellular functions.

Purpose of the Study:

  • To provide an overview of macropinocytosis origins and properties.
  • To summarize the roles of macropinocytosis in health and disease.
  • To highlight drug delivery systems utilizing macropinocytosis for internalization.

Main Methods:

  • Review of existing literature on macropinocytosis.
  • Analysis of biomimetic and synthetic drug delivery systems.
  • Discussion of clinical application challenges and future research directions.

Main Results:

  • Macropinocytosis enables the uptake of substantial fluid-phase drugs.

Pinocytosis

Cells use energy-requiring bulk transport mechanisms to transfer large particles or large numbers of small particles into or out of the cell. The cells envelop the particles in spherical membranes called vesicles or vacuoles. Vesicles that transport material into the cell are built from the cell membrane. These vesicles encapsulate external molecules and transport them into the cell in a process called endocytosis.
Pinocytosis ("cellular drinking") is one of three main types of...

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport

Drugs need to permeate cell membranes to reach their target sites after administration. Orally administered drugs must transcend intestinal epithelial membrane barriers to infiltrate the systemic circulation. Drugs with a molecular weight of less than 500 Daltons diffuse through gaps between neighboring cells, called paracellular pathways.
However, most drugs use the transcellular route, traversing directly through the cell membranes via two mechanisms: passive and active transport. Passive...

Vesicular Trasport: Endocytosis, Transcytosis and Exocytosis

Vesicular transport is a cellular process that encompasses the engulfment of particles or dissolved substances by cells. It involves endocytosis, transcytosis, and exocytosis.
Endocytosis is a cellular mechanism that involves the inward folding of the cell membrane to create vesicles that capture and transport large drug molecules. This process comprises two distinct methods: pinocytosis (often referred to as "cell drinking") and phagocytosis (often referred to as "cell...
