Summary
This study presents a new assay to measure how well macrophages engulf dying cells. This method helps researchers understand efferocytosis regulation by liver X receptor (LXR) signaling.
Area of Science:
- Immunology
- Cell Biology
Background:
- Efferocytosis is crucial for tissue homeostasis and involves phagocytic cells like macrophages.
- Liver X receptor (LXR) signaling in macrophages influences key molecules involved in efferocytosis.
Purpose of the Study:
- To develop and validate a sensitive and robust assay for measuring macrophage efferocytosis capability.
- To provide a tool for investigating the role of LXR signaling and other factors in efferocytosis.
Main Methods:
- The study optimized an assay using bone marrow-derived macrophages (BMDMs).
- The assay measures the engulfment capability of BMDMs towards apoptotic cells.
Main Results:
- A sensitive and robust efferocytosis assay was successfully established.
- The assay is suitable for evaluating genetically or pharmacologically modified BMDMs.
Conclusions:
- The developed assay provides a reliable method to study efferocytosis in macrophages.
- This tool facilitates research into the regulation of efferocytosis, particularly concerning LXR signaling.

01:17Phagocytosis of Apoptotic Cells
5.1K
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.

01:17The Extrinsic Apoptotic Pathway
8.4K
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...

01:31The Intrinsic Apoptotic Pathway
8.5K
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...

01:01Production Efficiency
18.3K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

00:46Trophic Efficiency
25.1K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

01:16Efficiency of The Carnot Cycle
3.7K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...
