Forced Transdifferentiation

Forced Transdifferentiation

Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

Bioreactor Controls-III

Bioreactor Controls-III

Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...

Background:

Adoptive immunotherapy using induced Tregs (iTregs) shows promise for autoimmune diseases.
Optimizing iTreg production is crucial for therapeutic efficacy.

Purpose of the Study:

To investigate the impact of substrate stiffness on human Treg induction.
To develop a simple approach for improving iTreg production.

Main Methods:

Conventional CD4+ T cells were activated on materials with varying elastic moduli.
Cells were cultured under suppressive conditions to induce Tregs.
Epigenetic modifications and suppressive capacity were analyzed.

Main Results:

Enhanced Treg induction was observed on softer substrates within 3 days.
This enhanced induction persisted for several weeks.
Substrate stiffness influenced epigenetic modifications and Treg suppressive function.

Conclusions:

Substrate stiffness is a critical factor in human Treg induction.
Softer materials promote both the quantity and suppressive quality of induced Tregs.
This finding offers a tunable method for enhancing Treg-based immunotherapy.
