Insights

Efficiently clearing dying cells is crucial for tissue health and disease. This review explores molecular signals on dying cells and their impact on immune cell clearance and therapies.

Area of Science:

  • Immunology
  • Cell Biology
  • Pathogenesis

Background:

  • Cell death and its clearance are vital for maintaining tissue homeostasis.
  • The process involves complex interactions between dying cells, bridging molecules, and engulfing cells.
  • Dysfunctional clearance contributes to various diseases.

Purpose of the Study:

  • To review recent advances in understanding molecular changes on dying cells.
  • To discuss how dying cells are recognized and cleared by phagocytes.
  • To explore the modulation of immune responses by dying cell clearance and its therapeutic implications.

Main Methods:

  • Literature review of recent research on cell death recognition and clearance.
  • Analysis of molecular mechanisms governing phagocyte interactions with dying cells.
  • Discussion of experimental cancer therapies targeting dying cell immunogenicity.

Main Results:

  • Dying cells display specific molecular changes that facilitate their recognition and engulfment.
  • Factors released by dying cells actively recruit phagocytes, such as macrophages.
  • Phagocytes employ distinct mechanisms to differentiate between live and dead cells.

Conclusions:

  • Understanding the molecular dialogue between dying cells and phagocytes is key to tissue homeostasis.
  • Clearance of dying cells significantly influences phagocyte immune responses.
  • Targeting dying cell immunogenicity offers promising strategies for cancer therapy.

B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
Antibody Actions01:26

Antibody Actions

Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
