A deadly form of skin cancer is able to fend off the body’s immune system, UK researchers have found.

Analysis of tumour and blood samples shows that melanoma knocks out the body’s best immune defence.

A potential test could work out which patients are likely to respond to treatment, the Journal of Clinical Investigation reports.

Cancer Research UK said the body’s response was a “complex puzzle”.

Previous work from the team at King’s College London showed that while patients with melanoma produced antibodies that could attack tumour cells, the immune system often seemed powerless to stop the cancer progressing.

The team in Oxford said their studies closely resemble the treatments that would be needed in people with degenerative eye disease.

Similar results have already been achieved with night-blind mice.

Experts said the field was advancing rapidly, but there were still questions about the quality of vision restored.

Patients with retinitis pigmentosa gradually lose light-sensing cells from the retina and can become blind.

Totally blind mice have had their sight restored by injections of light-sensing cells into the eye, UK researchers report.

An experimental “Trojan-horse” cancer therapy has completely eliminated prostate cancer in experiments on mice, according to UK researchers.

The team hid cancer killing viruses inside the immune system in order to sneak them into a tumour.

Once inside, a study in the journal Cancer Research showed, tens of thousands of viruses were released to kill the cancerous cells.

Experts labelled the study “exciting,” but human tests are still needed.

Rural communities across Africa may soon benefit from improved water supplies thanks to mobile phone technology.

UK researchers have developed data transmitters that fit inside hand pumps and send text messages if the devices break down.
