Maturation Pathway of Telomerase

An important step in the maturation pathway of telomerase has been discovered at the Stowers Institute’s Baumann Lab.  Telomerase uses part of an RNA subunit as a template to add telomeric DNA to the ends of chromosomes. The Baumann Lab found that this RNA subunit is first made as a longer inactive form that must be processed into a shorter mature form for telomerase to function.   The research is published in the Dec 5 issue of NATURE.

New Light Shed on Intracellular Molecular Motors

ScienceDaily (Dec. 15, 2008) — Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what “steers” these engines to their destinations. Now, researchers at the University of Rochester have shed new light on how cells accomplish this feat, and the results may eventually lead to new approaches to fighting pathogens and neurological diseases.  The mechanisms that control the molecular motors are quite different from what biologists have previously believed.   Read the full story in the latest issue of Cell.

New Therapies Possible with “Regulatory T Cells”

ScienceDaily (Dec. 10, 2008) — A study published by Elsevier this month in Clinical Immunology describes a new method that facilitates the induction of a specific type of immune suppressive cells, called ‘regulatory T cells’ for therapeutic use. These immune suppressive cells show great potential for the treatment of autoimmune diseases and improving transplantation outcomes. Regulatory T cells are an important part of the immune system and can play a suppressive role, but naturally occur in low numbers.  Michael Albert and colleagues from the Ludwig-Maximilians-University in Munich, Germany, describe a unique strategy that facilitates the induction of regulatory T cells ex vivo with subsequent expansion to numbers adequate for immunotherapy.  Using an inexpensive, fast and simple high-yield method they generated regulatory T cells from small amounts of peripheral blood which, potentially, could be transferred back into a patient enabling a clinically desired immune suppression.   For a copy of this article please contact Markus Library: call Alisa at 8957, or email librequest@rockefeller.edu
