VIP: New way to prevent spread of devastating diseases

VIP: New way to prevent spread of devastating diseases

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren’t working Continue reading

Protein appears to protect against bone loss in arthritis

Protein appears to protect against bone loss in arthritis

A small protein named GILZ appears to protect against the bone loss that often accompanies arthritis and its treatment, researchers report. Arthritis as well as aging prompt the body to make more fat than bone, and the researchers have previously shown GILZ can restore a more youthful, healthy mix. It also tamps down inflammation, a major factor in arthritis. Continue reading

Platelet-like particles augment natural blood clotting for treating trauma

Platelet-like particles augment natural blood clotting for treating trauma

A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries — and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets. The clotting particles, which are based on soft and deformable hydrogel materials, are triggered by the same factor that initiates the body’s own clotting processes Continue reading

Important regulators of immune cell response identified

Important regulators of immune cell response identified

In a collaborative study, scientists from the Florida campus of The Scripps Research Institute (TSRI) and the La Jolla Institute for Allergy and Immunology have developed a more effective method to determine how immune cells called T cells differentiate into specialized types of cells that help eradicate infected cells and assist other immune cells during infection. The new approach, published recently by the journal Immunity , could help accelerate laboratory research and the development of potential therapeutics, including vaccines. The method may also be used to identify the genes that underlie tumor cell development. Continue reading

Surprising discovery: HIV hides in gut, evading eradication

Surprising discovery: HIV hides in gut, evading eradication

Researchers at UC Davis have made some surprising discoveries about the body’s initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β).

From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

Rabies (and rabies virus, its causative agent) is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. Continue reading

Tissue regeneration using anti-inflammatory nanomolecules

Tissue regeneration using anti-inflammatory nanomolecules

Date: August 22, 2014 Source: Children’s Memorial Hospital Summary: Anyone who has suffered an injury can probably remember the after-effects, including pain, swelling or redness. These are signs that the body is fighting back against the injury. When tissue in the body is damaged, biological programs are activated to aid in tissue regeneration Continue reading
