| lipocortin | <protein> The name given to calcium-binding proteins believed to be secreted by macrophages that acts as an inhibitor of phospholipase A2 enzymes and has a possible role in mediating the antiinflammatry effects of steroids. Lipocortins are identified as proteins of the annexin class and their extracellular role is in some doubt. (18 Nov 1997) |

| lipofuscin | <protein> Brown pigment characteristic of ageing. Found in lysosomes and is the product of peroxidation of unsaturated fatty acids and symptomatic, perhaps, of membrane damage rather than being deleterious in its own right. (18 Nov 1997) |
| lipofuscinosis | Abnormal storage of any one of a group of fatty pigments. Ceroid lipofuscinosis, cerebral sphingolipidosis, late juvenile type. Neuronal ceroid lipofuscinosis, a group of diseases characterised by accumulation of abnormal pigments in tissue (previously classified as cerebral sphingolipidoses). Major subtypes include chronic juvenile form (Batten disease), slowly progressive behaviour and visual symptoms, autosomal recessive inheritance; acute, late infantile form (Bielschowsky disease); autosomal recessive inheritance; chronic adult form (Kufs disease), variable inheritance; acute infantile form (Santavuori-Haltia disease), fulminating motor and mental deterioration often associated with myoclonic seizures. Minor forms have also been described. (05 Mar 2000) |
