  • Computational paradigms studied by natural computing are abstracted from natural phenomena as diverse as self-replication, the functioning of the brain, Darwinian evolution, group behavior, the immune system, the defining properties of life forms, cell membranes, and morphogenesis. (wikipedia.org)
  • With obesity, the immune cells important for maintaining metabolic homeostasis are suppressed because immune cell function and immune cell amount are affected by excess fat accumulation in adipose tissue. (wikipedia.org)
  • In multiple sclerosis, the VLA-4 integrin is essential in the processes by which T-cells gain access to the brain by allowing the cells to penetrate the blood brain barrier that normally restricts immune cell access. (wikipedia.org)
