Summary
Class 1 Phosphoinositide-3-Kinases (PI3Ks) in macrophages regulate cellular responses to nutrients and metabolic stimuli. Understanding PI3K pathways is crucial for addressing obesity, diabetes, and inflammation.
Area of Science:
- Immunology and Metabolism
- Cellular Signaling Pathways
Background:
- Class 1 Phosphoinositide-3-Kinases (PI3Ks) are vital for cellular processes including proliferation, chemotaxis, insulin sensitivity, and immunity.
- Macrophages play critical roles in metabolic health and inflammation, particularly in adipose tissue.
Purpose of the Study:
- To provide a comprehensive overview of how macrophage-expressed PI3Ks and their downstream pathways control responses to metabolic stimuli.
- To highlight the role of PI3Ks in macrophage polarization, cellular identity, and function in metabolic contexts.
- To emphasize the significance of adipose tissue macrophages in obesity-associated insulin resistance and inflammation.
Main Methods:
- Review and synthesis of existing literature on PI3K signaling in macrophages.
- Focus on studies investigating PI3K involvement in metabolic regulation and inflammatory responses.
- Analysis of macrophage polarization and function in response to metabolic cues.
Main Results:
- Macrophage PI3Ks and their pathways are key orchestrators of cellular responses to metabolic stimuli and nutrients.
- These pathways influence macrophage polarization, cellular identity, and overall function.
- Adipose tissue macrophages are significantly impacted, contributing to insulin resistance and inflammation in obesity.
Conclusions:
- PI3K-dependent signaling in macrophages is central to metabolic homeostasis and inflammation.
- Targeting PI3K pathways in macrophages offers potential therapeutic strategies for metabolic and inflammatory diseases.
- Further understanding of PI3K wiring in macrophages is essential for treating conditions like obesity, type 2 diabetes, and chronic inflammation.

01:22PI3K/mTOR/AKT Signaling Pathway
5.4K
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...

02:26NF-κB-dependent Signaling Pathway
9.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:25cAMP-dependent Protein Kinase Pathways
8.3K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

01:19Absorption of Nutrients
2.8K
Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

This video demonstrates an assay to examine the toll-like receptor(TLR)-dependent activity of the transcription factors nuclear factor-kappa-B (NF-κB) and activator protein-1 (AP-1) in macrophages. The TLRs trigger a pro-inflammatory signaling cascade upon recognizing damage-associated molecular patterns (DAMPs), activating NF-κB and AP-1. The engineered reporter macrophages produce secreted embryonic alkaline phosphatase (SEAP) enzyme upon NF-κB and AP-1 activation, which is...
