Bristle worms use specialized cells called chaetoblasts to form bristles, similar to a technical 3D printer. The microvilli on these cells produce chitin, the primary building material for the bristles.
Researchers found that a vaccine against the toxin produced by E. coli protects infant mice from intestinal damage, suggesting it could boost global efforts to combat childhood malnutrition. Vaccinating kids against E. coli diarrhea may prevent long-term effects like stunting and micronutrient deficiencies.
Researchers found that increasing food amount elevates intestinal absorptive surface and function due to enhanced PPARα expression. Food restriction reverses this process, suggesting potential avenues for limiting obesity.
Researchers at TU Wien have discovered that tiny traction forces on the molecular level are essential for the recognition of antigens by T-cells. This new understanding could lead to a deeper understanding of immune system function and potentially new treatment strategies.
A team of Penn researchers has pinpointed the underlying mechanism leading to vision loss in Best disease, a condition affecting central vision. They discovered that differences in supporting structures between rods and cones contribute to lesion development in the macula.
Two independent groups studying gut microvilli have found striking parallels with the protein complexes that organize inner ear hair cell stereocilia. The findings suggest that evolution may have borrowed successful biological structures to create new functions, connecting the gut and the ear.
Researchers found that brush border microvilli and stereocilia share strikingly similar interaction modes, despite different functions. The study reveals a common mechanism for the formation of tip-link complexes in both structures.
Researchers have discovered that intestinal cells use adhesion molecules to build the nutrient-absorbing brush border, a critical structure for absorbing nutrients and defending against pathogens. The findings provide new insights into intestinal pathologies associated with inherited and infectious diseases.
Researchers at Purdue University have discovered that resistant wheat plants stave off attacks by Hessian fly larvae by destroying their midgut and preventing nutrient absorption. The study found that the midgut disruption is caused by a toxic substance called lectin, which is produced by the plant in response to the fly's presence.
A study by McConnell et al. reveals that intestinal microvilli extend their function beyond nutrient absorption, releasing vesicles packed with enzymes into the gut lumen for enhanced nutrient breakdown and defense against pathogens like lipopolysaccharide
A common fruit fly has helped scientists discover a protein crucial for the insect's eggshell formation, which could be a potential target for pesticides. The protein, called palisade, is essential for the formation of the vitelline membrane, a key component of the eggshell.
Researchers discovered Giardia's attachment mechanism relies on an osmotic suction cup, which can be disrupted by 'tonic shock'. The parasite's grip on intestinal tissue can be broken using a timed pattern of high and low tonicity, suggesting new treatment options.
Researchers discovered that molecular motors play a crucial role in shedding membrane from the tips of microvilli, speeding up nutrient processing. This finding has implications for understanding gastrointestinal physiology and potential new treatments for diseases.
The study characterizes lymphocyte microvilli, dynamic structures that alternate between assembly and disassembly. Disrupting these receptors could lead to a less toxic form of immune suppression and prevent metastasis in cancer cells.
