Summary
The mammalian target of rapamycin (mTOR) network regulates innate immune cell metabolism and responses. Understanding mTOR
Area of Science:
- Immunology
- Cellular Metabolism
- Molecular Biology
Background:
- The innate immune system maintains tissue homeostasis and responds to insults.
- Immune cell activation requires metabolic support for migration, proliferation, and mediator production.
Purpose of the Study:
- To review the role of mammalian target of rapamycin (mTOR) in innate immune cell effector responses.
- To elucidate how mTOR coordinates cellular metabolism and inflammatory responses.
Main Methods:
- Literature review focusing on mTOR's functions in innate immunity.
- Analysis of mTOR's impact on cellular metabolism, translation, and immune cell functions.
Main Results:
- mTOR reconfigures cellular metabolism to support innate immune responses.
- mTOR regulates key processes including translation, cytokine production, antigen presentation, macrophage polarization, and cell migration.
- The mTOR network acts as a rheostat, linking cellular activation to nutritional status.
Conclusions:
- mTOR is a critical regulator of innate immune cell effector functions.
- Metabolic coordination by mTOR optimizes inflammatory responses.
- Understanding mTOR's role in myeloid cells offers insights into immunity in health and disease.

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

6.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:20The JAK-STAT Signaling Pathway
13.9K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:31Regulation of the Unfolded Protein Response
3.2K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

3.0K
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...
