In vitro interaction of LDL, anti-lipoprotein IgA and human fibroblasts.
Human LDL were bound and internalized by cultured human fibroblasts. When an antilipoprotein IgA kappa from a case of myeloma with hyperlipidemia and xanthomatosis was introduced into the system, LDL uptake dropped by 50% but LDL binding to fibroblasts was unchanged. In the same system, IgG and IgA controls were inactive.
