Summary
Regulated cell death (RCD) pathways are crucial for multicellular life. Synthetic biology tools now enable precise RCD induction, overcoming challenges in studying interconnected cell death mechanisms in cells and animals.
Area of Science:
- Cellular Biology
- Immunology
- Developmental Biology
Background:
- Regulated cell death (RCD) removes unwanted cells, vital for organism development, homeostasis, and immunity.
- Multiple RCD forms exist (apoptosis, necroptosis, pyroptosis, ferroptosis), with characterized signaling pathways.
- RCD pathways exhibit plasticity and interconnectivity, complicating isolated study.
Purpose of the Study:
- To review advances in synthetic biology tools for targeted RCD induction.
- To highlight the advantages and limitations of these novel RCD research tools.
- To discuss the application of these tools in studying RCD in biological systems.
Main Methods:
- Discussion of chemogenetic and optogenetic tools for RCD induction.
- Analysis of synthetic biology approaches for precise control of cell death.
- Review of existing literature on RCD pathway interconnectivity and plasticity.
Main Results:
- Synthetic biology tools offer targeted RCD induction, overcoming limitations of classical methods.
- These tools enable the study of RCD pathways in isolation and in complex biological contexts.
- Demonstrated advantages and limitations of chemogenetic and optogenetic RCD induction methods.
Conclusions:
- Synthetic biology tools are powerful for dissecting complex RCD signaling.
- Targeted RCD induction facilitates research into cell death mechanisms and immune responses.
- These advancements are crucial for understanding RCD in development, homeostasis, and disease.

01:30Overview of Cell Death
7.4K
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...

01:18Autophagic Cell Death
3.4K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:17The Extrinsic Apoptotic Pathway
6.4K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

01:30Apoptosis
11.6K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:31The Intrinsic Apoptotic Pathway
6.6K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
