Novel CRISPR platform to decode the immune system

Date: 11th February 2022 The immune system is a critical biological network of processes that protects an organism from disease, and depends on the ability to distinguish self from non-self, a role driven by antigens.  In humans, T cells respond to antigen stimulation together with the production of cytokines however,…

Novel CRISPR Tool Activates Instead of Editing Human Immune Cell Genes

Scientists at Gladstone Institutes and UC San Francisco (UCSF) say they have co-opted the CRISPR-Cas9 system to forcibly activate genes—rather than edit them—in human immune cells. The method, known as CRISPRa, lets them discover genes that play a role in immune cell biology more thoroughly and rapidly than previously possible,…

Researchers use CRISPR activation method to reveal “Rosetta Stone” of immune cell function

SAN FRANCISCO, CA—February 4, 2022—CRISPR genome editing has served as a powerful tool for deleting or altering DNA sequences and studying the resulting effect. Now, researchers at Gladstone Institutes and UC San Francisco (UCSF) have co-opted the CRISPR-Cas9 system to forcibly activate genes—rather than edit them—in human immune cells. The…

Increasingly efficient production of human pluripotent stem cells

Reliable production of high-quality iPS cells enables their increasingly efficient utilization in biomedical applications. Credit: Ras Trokovic, University of Helsinki Researchers at the University of Helsinki have developed a new, faster and more reliable technique for reverting human cells to the stem cell state. Pluripotent stem cells are a key…

New Techniques and Complex Models

CRISPR systems that rely on inactivated Cas enzymes—that is, dead Cas (dCas) enzymes—never looked more alive. They harness the targeting power associated with CRISPR—but not the double-strand cuts. As such, they give researchers new ways to interrogate and manipulate gene function. Possibilities include CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa)…
