Overview of Exosomes01:36

Overview of Exosomes

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...
Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Lipid-derived Compounds in the Human Body01:31

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Overview of the Vascular System01:20

Overview of the Vascular System

The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Area of Science:

  • Cell Biology
  • Immunology
  • Biochemistry

Background:

  • Extracellular vesicles (EVs) mediate intercellular communication via their phospholipid bilayers.
  • Lysophospholipids, generated by secretory phospholipase A2 (sPLA2), can suppress immune responses and attenuate cytokine storms.

Purpose of the Study:

  • To elucidate the mechanisms of inflammation regulation involving EVs, phospholipids, and sPLA2.
  • To understand the role of sPLA2 in modulating immune responses through phospholipid metabolism.

Main Methods:

  • Analysis of EV composition and function.
  • Investigation of sPLA2 activity in cellular models.
  • Assessment of lysophospholipid generation and its impact on immune cells.

Main Results:

  • EV phospholipid bilayers are critical for intercellular signaling.
  • sPLA2 activity contributes to immune suppression by generating immunosuppressive lysophospholipids.
  • Lysophospholipids can dampen inflammatory responses like cytokine storms.

Conclusions:

  • EVs, phospholipids, and sPLA2 form a regulatory axis controlling inflammation.
  • Targeting this axis may offer therapeutic strategies for immune dysregulation and inflammatory diseases.
