UConn Expert Member of Global Commission Calling on World to Improve Sickle Cell Disease Care

Global mortality from sickle cell disease may be nearly 11 times higher than recorded, says new Commission of world experts published in The Lancet Haematology journal.

Shorter Telomeres Point to Increased Alzheimer’s Risk

If longer telomeres actually reduce Alzheimer's risk, it’s one more reason for people to adopt a healthy lifestyle

Two men smile at the camera as the one on the right loads a cartridge full of samples into a large piece of laboratory machinery.

Microscopy on Ice with UConn Health’s New Cryogenic Equipment

Cryogenic electron microscopy, which can produce 3D pictures of minute quantities of biological material, is a new forefront of research capabilities at UConn School of Medicine

Three sections of optic nerve that were injured by crushing (the white diamond on the far left of each nerve marks the crush point.) The lower two nerves each express genes (Dynlt1a or Lars2) newly identified by the Trakhtenberg lab as promoting nerve axon regeneration. The axons carry the bright green dye. The insets to the right show how much more axon regrowth is occurring in the nerves that express the regeneration genes, and how no regrowth happens in the normal control (top).

Report: Mental Health Crises Spike Among Youth

Suicide related emergency room visits for young people have increased every year since 2011

Load it up. Column (a) shows how the high dose, slow release microneedle antibody patch (MA) works. PLGA is a biodegradable polymer that can be tuned to degrade faster or slower. The middle image shows microneedles made of differently tuned PLGA represented by different colors. The graph on the bottom shows how the patch keeps blood levels of antibodies (Ab) in a certain range, with little spikes as the different PLGA microneedles dissolve and release their antibodies into the bloodstream over 30 days. Column (b) shows the high dose powder-filling method the team developed. It can deliver doses of 4 to 5mg of antibodies per square centimeter of patch. The traditional technology shown in column (c) can deliver only much lower doses.

Less Painful, More Convenient Antibody Treatments

A timed-release patch made of biodegradable polymer could make antibody treatments more accessible and safer

Depressed, and Aging Fast

UConn Center on Aging researchers have found that older adults suffering from depression age faster than their peers

The figure’s x-axis compares two subpopulations of microglia cells (the brain’s ‘waste disposal team’.) One group causes inflammation; the other group repairs damage. The figure’s y-axis shows that the T-cell receptor signaling pathway (a known major immune-regulatory mechanism) is significantly more active in the blue cells repairing damaged tissue. On the other hand, the immune system is relatively suppressed in the red cells causing inflammation.

Brain’s Garbage Collectors May be to Blame in Alzheimer’s

Instead of being the primary cause of the disease, perhaps the plaques and tangles of Alzheimer’s are a symptom
