Our immune system comprises a great variety of cell types and each of these groups is specialized in separate and defined actions. 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 […]

Interior of a human blood vessel. Something looks wrong, very wrong. Bacteria have entered the circulation, and the immunological system is reacting. All the alarms are on fire, while an army of white blood cells comes by, getting ready to unleash hell on the invaders. Suddenly, among these security agents, a neutrophil stands out. It […]
Diagnosis is one of the trickiest steps in disease management for many diseases, ranging from some types of cancer to rare diseases or neurodegenerative disorders, like Alzheimer’s for instance. Even though we have been hearing long about the disease, to date the only reliable diagnosis comes from a postmortem brain analysis and the finding of […]
The immune system is composed of a considerable variety of cell types with different functions. One of the most important cells involved in the innate immunity are the macrophages . These cells have a wide spectrum of functions: from bacteria-killing function to wound healing properties. Classically the macrophages according to their functions have been classified […]
Aging is one of those topics mankind is always trying to understand, especially whether it can be reversed or stopped. With increasing age come not only alterations in appearance, but also associated changes like the degeneration of tissues such as muscles, bone and neural tissues or a higher predisposition for disease. In recent years, we […]
