Five facts you need to kow about HIV/AIDS

HIV infection is often diagnosed through rapid diagnostic tests (RDTs), which detect the presence or absence of HIV antibodies. 

T cells use 'handshakes' to sort friends from foes

T cells, the security guards of the immune system, use a kind of mechanical "handshake" to test whether a cell they encounter is a friend or foe, according to a new study that may help develop immune therapies for cancer.

Sound sleep boosts immune system 'memory' too

 A good night's sleep not only strengthens your memory but also strengthens the response-memory of your immune system when it comes to killing bad bacteria and viruses as they enter your body, new research reveals.

Molecule key to shock-and-kill strategy against HIV

A new molecule that binds HIV-infected cells to the immune system's killer T cells could become a key part of a shock-and-kill strategy to clear the deadly infection, scientists say.

Link between powerful gene regulatory elements and autoimmune diseases revealed

 A team of researchers has discovered the genomic switches of a blood cell key to regulating the human immune system.

Personalized cancer vaccines come one step closer to reality

A new study has brought personalized cancer vaccine approach one step closer to reality.

In a first, living organ created from lab-grown cells

In a significant breakthrough, British scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal that can lead to new treatments for people with a weakened immune system.

Low cholesterol in immune cells tied to slow HIV progression

People infected with HIV whose immune cells have low cholesterol levels experience much slower disease progression, even without medication, according to a new research.

Taking `scissors` to immune cells shows HIV promise

A new gene therapy approach that engineers a person`s T cells so that they become resistant to the human immunodeficiency virus has shown early signs of success, researchers said Wednesday.

Simple blood test may determine peanut allergy

Soon, a simple blood test may be able to tell whether a person`s allergy for peanuts has totally been shut off.

Donor immune cells linked to rejection in facial transplant

From the world`s first facial `replant` in 1994 on Sandeep Kaur, a nine-year-old Indian girl, to the now common full facial transplantation, the world has moved quite a lot.

Special immune cells keep TB in control: Study

A special class of immune cells called `invariant natural killer T cells` keep the deadly tuberculosis infection in check - a heartening news for India that has the most number of tuberculosis cases in the world.

Scientists develop new method for treating pancreatic cancer

British researchers have developed a new method for treating pancreatic cancer which enables the body`s immune system to attack and kill cancer cells.

Human brains hard-wired for `calm rural life`

A new study has revealed that that human may be hard-wired to enjoy the peace in the countryside and confused in cities- even if they were born and raised in an urban area.

Experimental drug could potentially treat lung cancer

An experimental drug that has shown promise in the treatment of melanoma has also shown early potential as an effective treatment for patients with non-small cell lung cancer.

How cancer`s `invisibility cloak` works

T cell researchers have discovered how a lipid secreted by cancer tumours stops the immune system from mounting an immune response against it.

Universal cure for HIV gets tougher

Researchers have claimed that the amount of potentially active, dormant forms of HIV hiding in infected immune T cells may actually be 60-fold greater than previously thought.

Women who smoke could disrupt prenatal development of babies

A new study has demonstrated how exposure to tobacco smoke affects the development of human immune system on molecular level.

Universal flu vaccine closer to reality

Scientists including an Indian-origin are now closer to developing a universal flu vaccine, after they used the 2009 pandemic as a natural experiment to study why some people resist severe illness.

Tumours disable immune cells by using up sugar

Cancer cells` appetite for sugar may have serious consequences for immune cell function, a new study has found.
