Immune-mediated neuropathies: etiology and pathogenic relationship to aging processes.
Immune-mediated peripheral neuropathies are more frequent in aged populations. Equally, underlying diseases such as vasculitis and paraproteinemia are more prevalent in the elderly. Accumulating evidence is linking the aging process of the immune system, immunosenescence, to the susceptibility of older individuals for paraproteinemic, vasculitic and inflammatory demyelinating neuropathies. Why an individual develops a particular disease is likely due to a number of factors. These include mutations in neural tissue-specific B and T cells, decreased central tolerance, increased proinflammatory environment due to cytokine shifts and higher functional capacity of innate immune cells.
