Special Issue Information
Dear Colleagues,
Background and Significance
Insect silk—a natural marvel of strength, elasticity, and biocompatibility—holds transformative potential for biomedicine, sustainable textiles, and advanced composites. Despite this promise, reproducing its properties synthetically remains elusive. Critical knowledge gaps persist in two interconnected domains:
- Silk Gland Development: It is unclear how developmental signals sculpt silk’s gland structure with cellular specialization across insect species.
- Silk Protein Synthesis and Processing: The molecular choreography of fibroin/sericin production, modification, storage, and transport is also significant.
Understanding these mechanisms is essential to bridge the performance gap between natural and artificial silk.
Aims of this Special Issue
This Special Issue, “New Mechanisms and Insights into Insect Silk Gland Biology and Silk Production”, targets unresolved questions in the interface between biology and materials science.
- Organ Development: Genetic/epigenetic networks guiding silk gland morphogenesis, cell differentiation, and regeneration need to be found.
- Protein Synthesis Mechanics: Ribosomal dynamics, co-translational folding, and PTMs (e.g., glycosylation, phosphorylation) that dictate silk protein stability need to be ascertained.
- Secretion and Storage: Mechanisms preventing aggregation in the gland lumen (e.g., chaperones and ion homeostasis) need to be identified.
- Fiber Spinning Triggers: The role of pH shifts, metal ions, and shear forces in liquid-to-solid transition also needs to be determined.
Impact
This research collection will establish foundational knowledge for designing bioinspired silk systems and advance fields such as regenerative medicine (smart scaffolds) and the effective implementation of a materials circular economy. Insights into organ development and protein synthetic machinery will accelerate breakthroughs in synthetic biology and precision biomaterial engineering.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
