A protein sequence associated with Huntington’s disease may become life-saving vaccine component

... First, he noticed that small aggregates formed by an antigen fused to a polyQ tail resembled the droplets that conventional adjuvants formed with antigenic peptides exposed on their surface. Dr. Shneider hypothesized that these polyQ containing aggregates were easily taken up by antigen-presenting ...

Paracetamol, one of most used analgesics, could slow down bone growth

... process). Application of this plasma gel on bones accelerates their growth, without affecting other cell parameters such as the cell cycle or the antigenic profile. It is therefore an easy technique which involves few risks for the patient, who will recover from bone defects more quickly. Even ...

H5N1 vaccine could be basis for life-saving stockpile

... Scientists at St. Jude Children's Research Hospital have announced that a vaccine they developed a few years ago against one antigenic variant of the avian influenza virus H5N1 may protect humans against future variants of the virus. Vaccines based on this model might therefore be ...

New factor implicated in allergy and asthma attacks

... species, and resulted in a much smaller increase in numbers of inflammatory immune cells. "We showed that you need both oxidative stress and antigenic exposure to get a robust allergy or asthma attack, and also that the first few minutes of the exposure are critical," Boldogh said. "The antigen ...

Breast tumors in mice eradicated using cancer vaccine

... of helper T cells, others survive by escaping into the cytosol of the cell. This is important because the antigen-processing pathway that feeds antigenic peptides to the surface of the cell for recognition by killer T cells is generated in this cellular compartment. "We reasoned that if we could get ...

Source of molecular triggers in cutaneous T cell lymphoma identified

... CTCL as a separate category of lymphoma thirty years ago. The Yale research group reported that, like all T cells, the cancerous CTCL cells require antigenic stimuli delivered by specialized dendritic cells of the epidermis, referred to as Langerhans cells (LC), in order to replicate. To determine the ...
