Summary
Fatty acid metabolism, including biosynthesis, oxidation, and uptake, significantly impacts T and B cell functions. Microbiota-derived fatty acids also play a crucial role in adaptive immunity.
Area of Science:
- Immunology
- Metabolism
- Cell Biology
Background:
- Fatty acids (FAs) are essential for cell membrane structure and biological functions.
- Emerging research highlights the critical role of FA metabolism in adaptive immunity.
Purpose of the Study:
- To review the key processes of FA metabolism (biosynthesis, oxidation, uptake) and their influence on T and B cell functions.
- To explore the connection between microbiota-derived FAs, short-chain FAs (SCFAs), and adaptive immunity.
- To discuss current controversies and challenges in the field of FA metabolism and immunity.
Main Methods:
- Literature review of FA metabolism and adaptive immune response.
- Analysis of FA biosynthesis, oxidation, and uptake pathways.
- Examination of the role of microbiota-derived FAs and SCFAs.
Main Results:
- FA metabolism pathways directly regulate T and B cell functions during immune responses.
- Microbiota-derived FAs, including SCFAs, are integral to adaptive immunity.
- Specific FA metabolic processes are critical for adaptive immune cell differentiation and function.
Conclusions:
- Fatty acid metabolism is a key regulator of adaptive immunity.
- Understanding FA metabolism offers potential therapeutic targets for immune modulation.
- Further research is needed to resolve existing controversies and address challenges in the field.

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Microbial membranes exhibit remarkable diversity in lipid composition, reflecting evolutionary adaptations to various environmental conditions. The three domains of life—Bacteria, Archaea, and Eukarya—synthesize membrane lipids through distinct biosynthetic pathways, leading to fundamental structural differences that impact membrane stability, function, and adaptability.Fatty Acid-Based Lipids in Bacteria and EukaryaBacteria and eukaryotes share a common fatty acid biosynthesis...

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
