T cells activated to fight HIV basis for dendritic cell therapeutic vaccine

...later this year. "The goal of the approach is to teach killer T cells to more efficiently find, detect and destroy HIV infected cells. Our vaccine, as an immunotherapy, is custom-designed to target the unique virus that has evolved in each individual being treated. A patient's own dendritic cells togethe...

UWM brain research supports drug development from jellyfish protein

...ed learning and memory deficits. These tasks first teach rodents to associate one stimulus with another and then test their memory of the association. During training, the stimuli are separated by a brief period of time, which requires the animal to maintain a memory of the first stimulus. The "stimulus fr...

Tracing the formation of long-term memory

... Davis and his colleagues used spaced training to teach the flies to associate an odor with a mild electric shock. This method gives the fly a training trial, then a rest and then another trial. The rest is critical in inducing long-term memory that can last days. In this study, the five spaced trials pro...

Why doesn't the immune system attack the small intestine?

...ly sensitive to microbial agents such as bacteria, teach T cells to resist attacking healthy intestinal cells." In the new study, Turley and her colleagues found that, in fact, dendritic cells aren't essential in creating tolerance in T cells. Instead, and unexpectedly, tolerance is produced by stromal c...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...nic stem cell research was absolutely necessary to teach us how to do this." Embryonic stem cells have been engineered to produce cardiac, neural, blood, lung and liver progenitor cells that perform many of the functions needed to help replace cells and tissues injured by many diseases, the paper note...

New vaccine prevents CMV infection and disease in mice

...ng the host’s immune responses. We found a way to teach the host immune system to not be tricked by the virus.” She added that the next step is to apply this strategy to create a vaccine for use in humans. CMV is a virus that, while carried by the majority of adults in the United States, can remain do...
