Summary
Bile acids (BAs) regulate metabolism and immunity by activating receptors like FXR and TGR5. Targeting BA signaling offers potential therapies for metabolic diseases linked to BA network dysfunction.
Area of Science:
- Metabolic and immune system interactions
- Gut-liver axis
- Bile acid signaling pathways
Background:
- Bile acids (BAs) are synthesized in the liver and modified by gut microbiota, forming a dynamic pool.
- BAs act as signaling molecules, regulating metabolic and immune processes via nuclear (FXR) and membrane (TGR5) receptors.
- Dysregulation of the BA signaling network is implicated in metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes.
Purpose of the Study:
- To review the dynamic composition of the bile acid pool.
- To elucidate the integrated regulatory roles of bile acid signaling networks in health and disease.
- To highlight emerging therapeutic strategies targeting bile acid signaling for metabolic and immune-mediated diseases.
Main Methods:
- Literature review of bile acid synthesis, metabolism, and signaling.
- Analysis of the role of bile acids in metabolic and immune homeostasis.
- Exploration of therapeutic targets within the bile acid signaling network.
Main Results:
- Bile acid pool composition dynamically influences metabolic responses.
- Bile acids integrate metabolic and immune functions through receptor activation (FXR, TGR5).
- Targeting bile acid signaling, including FXR agonists and TGR5 modulators, shows therapeutic promise.
Conclusions:
- Bile acid signaling is a critical systemic homeostatic network.
- Dysregulation of this network contributes to MASLD and other metabolic disorders.
- Emerging therapies targeting bile acid signaling present potential for treating metabolic and immune-mediated diseases.

Endocrine Signaling
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
Chemical Signaling in the Endocrine System
A signaling cascade is a series of events that facilitates the transmission of information within or between cells, culminating in a targeted response in the recipient cell. As chemical messengers, hormones are pivotal in initiating and modulating these intricate signaling cascades based on their solubility.
Lipid-soluble hormones, such as steroid hormones, demonstrate an intracellular action. These hormones traverse cell membranes due to their lipid nature. Once inside the target cell, they...

Autocrine Signaling
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

Bile
Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.

Liver Physiology
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can also...

Overview of Cell Signaling
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...
