Sickle Cell Disease

Sickle-cell disease, or sickle-cell anaemia (or drepanocytosis), is a life-long blood disorder characterized by red blood cells that assume an abnormal, rigid, sickle shape. Sickling decreases the cells' flexibility and results in a risk of various complications.

Understanding Sickle Cell Disease

World Sickle Cell Day is June 19 and was created by the United Nations in 2006 to raise global awareness for sickle cell disease as a public health problem. Sickle cell disease is an extremely debilitating medical condition.

Targeted inhibition of a 'signal jammer' protein may improve tumor response to immunotherapy

Targeted inhibition of a "signal jammer" protein may improve how tumors respond to immunotherapy. Published today in Nature, a new study demonstrates how some cancer cells use the protein voltage-dependent anion channel 2 (VDAC2) like a signal jammer to prevent the body's anticancer systems from communicating with the immune system.
