Boys suffering from X-linked adrenoleukodystrophy (X-ALD), a devastating neurodegenerative disease, have been cured with gene therapy.

Dr. Estébanez’s research line focuses in the latter feature. T he […]

Macrophages play an essential role within this defence system by enhancing the immune response. In particular, they are in charge of “swallowing” (technically speaking, fagocyting) waste products, foreign materials and microorganisms. In addition […]
The immune system is a complex network that recognises foreign substances in the body. When it detects an alien substance (antigen), it creates antibodies to attack and destroy it. This system protects vertebrates against viruses, bacteria, fungi and other parasites, and is the reason for the “rejection” after organ transplants. When we have cancer, our […]
