Overview of Exosomes01:36

Overview of Exosomes

2.9K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Vesicular Trasport: Endocytosis, Transcytosis and Exocytosis

1.8K
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...

Cell Inclusions01:27

Cell Inclusions

250
Prokaryotic cells possess a variety of inclusions that play crucial roles in nutrient storage, metabolic processes, and environmental adaptation. These structures enable bacteria to thrive under fluctuating environmental conditions by storing essential resources and optimizing their metabolic efficiency.Carbon Storage: Poly-β-Hydroxybutyric Acid and Glycogen GranulesBacteria frequently store excess carbon in specialized granules. Poly-β-hydroxybutyric acid (PHB) granules are lipid...

Lysosomes01:31

Lysosomes

20.5K
Lysosomes are membrane-enclosed spherical sacs derived from the Golgi apparatus. The most important function of the lysosome is degrading macromolecules and biological polymers that are released during membrane trafficking events such as the secretory, endocytic, autophagic, and phagocytic pathways. The degradation is carried out by several hydrolytic enzymes active in an acidic environment of the lysosomal lumen. These acid hydrolases are involved in cellular processes such as cell signaling,...

Overview of Secretory Vesicles01:33

Overview of Secretory Vesicles

8.8K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...
