Summary
Removing primary cilia in adult mice, including those in POMC neurons, triggers overeating. This leads to the development of obesity and kidney disease.
Area of Science:
- Cell biology
- Neuroscience
- Physiology
Background:
- Primary cilia are crucial cellular organelles involved in sensing the cellular environment.
- Dysfunction of primary cilia is implicated in various diseases, but their role in regulating feeding behavior is not fully understood.
Purpose of the Study:
- To investigate the role of primary cilia in regulating feeding behavior and metabolic homeostasis.
- To determine the consequences of primary cilia ablation in specific neuronal populations on eating patterns and associated pathologies.
Main Methods:
- Utilizing genetic mouse models to selectively knock out primary cilia in adult tissues and POMC-expressing neurons.
- Behavioral analysis to quantify food intake and body weight changes.
- Histopathological examination of kidneys to assess disease development.
Main Results:
- Ablation of primary cilia in adult mouse tissues induced hyperphagia (uncontrolled eating).
- Selective removal of primary cilia from POMC neurons also initiated excessive feeding behavior.
- Mice with primary cilia deficiency developed significant obesity and kidney disease.
Conclusions:
- Primary cilia play a critical role in suppressing overeating and maintaining metabolic balance.
- POMC neurons' primary cilia are essential regulators of appetite control.
- Primary cilia dysfunction is a potential driver of obesity and associated kidney pathologies.

01:05Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

01:30Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
01:22Microtubules in Signaling
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
01:24Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
00:55Microvilli
Microvilli are tiny finger-like projections found on the surface of certain cells. Their purpose is to increase the surface area of the cell's apical surface, resulting in more effective absorption or secretion of substances.
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity to...
