Summary
Spider spinnerets exhibit complex movements during silk production. Understanding these intricate kinematics in spiders like Badumna longinqua can inspire biomimetic multiple fiber spinning technologies.
Area of Science:
- Biomaterials Science
- Zoology
- Mechanical Engineering
Background:
- Spider silk is valued in material science and medicine, but its production mechanics are poorly understood.
- Spiders utilize diverse silk types, forming complex multi-fibre systems for prey capture, particularly in cribellate spiders.
Purpose of the Study:
- To describe the spinneret kinematics involved in the cribellate spinning process of the grey house spider, Badumna longinqua.
- To establish a foundation for understanding general spider spinneret kinematics and inspire biomimetic applications.
Main Methods:
- Detailed kinematic analysis of spinneret movements during the cribellate spinning process.
- Observation and description of spatial movements and temporal contact points of spinnerets.
Main Results:
- The study elucidates the sophisticated and precise spatial movements of spinnerets during silk production.
- Specific temporal contact points between spinnerets were identified as crucial for fibre assembly.
Conclusions:
- Spinneret kinematics are highly complex and essential for the formation of functional spider silk.
- This research provides insights into spider silk assembly and offers potential for biomimetic multiple fiber spinning systems.

01:14Generation of Straight or Branched Actin Filaments
3.4K
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

4.4K
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...

02:50Spindle Assembly
4.0K
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...

01:35Disassembly of Intermediate Filaments
2.4K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.

01:18Actin Treadmilling
9.1K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...

01:19The Structure of Intermediate Filaments
5.0K
The intermediate filaments are one of three widely studied cytoskeletal filaments. They are so named as their diameter (10 nm) is in between that of microfilaments (7 nm) and the microtubules (25 nm). These filaments are highly stable and can remain intact when exposed to high salt concentrations and detergents. These filaments are responsible for providing stability and mechanical support to the cells. They also help in cell adhesion and maintaining tissue integrity.
