Scientists Discover How Snails Tune Mucus Properties Using Collagen and Calcium
Key points
- Collagen and calcium determine snail mucus properties.
- Snails secrete different mucus types for specific functions.
- Research focused on the grove snail (Cepaea nemoralis).
- Mucus has potential in cosmetics and drug delivery.
Mechanism of Snail Mucus Tunability Identified
A team of German scientists has determined the mechanism by which snails achieve the tunability of their mucus. Their research, published in the journal Science, indicates that collagen and calcium interact to create the varying mechanical properties observed in snail slime. This finding explains how snails can produce different types of mucus tailored for specific functions.
Diverse Functions of Snail Mucus
Snail mucus is primarily composed of water, with mucins (glycoproteins) and complex carbohydrates contributing to its viscous texture. Snails secrete various types of mucus, each serving a distinct purpose. For instance, some mucus acts as a lubricant for locomotion, while other types function as adhesives to help the snail cling to surfaces. A hydrating version protects the snail's skin, and a calcite-containing epiphragm seals the shell during hibernation for protection.
Research Focus on Grove Snails
The research specifically focused on the grove snail, also known as the lemon snail (Cepaea nemoralis). This species was chosen because it secretes five different kinds of mucus, each with distinct functions. These include a lubricant for movement, an adhesive mucus, and the epiphragm layer used during winter hibernation.
Potential Applications of Snail Mucus
Beyond its natural biological roles, snail mucus is recognized for its potential in various applications. It is already valued in some skincare products for its anti-inflammatory and anti-aging properties. Additionally, the unique characteristics of snail mucus suggest its potential utility in drug delivery systems, building on previous research that explored its wound-healing and anti-inflammatory effects when combined with gold nanoparticles.
