Summary Immunoglobulin light chain (AL) amyloidosis is a rare and underdiagnosed life-threatening systemic disease, primarily caused by insoluble depositions of misfolded monoclonal chains. The paraprotein originates from small clonal B‑cell or plasma cell population. If left undetected the can induce number complications based on organ damage. most dangerous dysfunction emerges cardiac involve...

we discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. th e most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. moreover, since the systemic involvement of the di...

1. A method for the isolation of a new enzyme, myosin light-chain phosphatase, from rabbit white skeletal muscle by using a Sepharose-phosphorylated myosin light-chain affinity column is described. 2. The enzyme migrated as a single component on electrophoresis in sodium dodecyl sulphate/polyacrylamide gel at pH7.0, with apparent mol.wt. 70000. 3. The enzyme was highly specific for the phosphor...

Identification of the immunogens responsible for the production of pathogenic autoantibodies is a major problem in the field of autoimmunity. In the principal diseases that are thought to involve autoimmunization, rheumatoid arthritis, type I diabetes, and multiple sclerosis are examples, the instigating stimulus is unknown. Another example of the gap in our knowledge of disease-causing immunog...
