According to one study, knockout mice are not viable and heterozygous knockout mice display impaired phagocytosis of apoptotic cells (PubMed:16908670). However, another study shows that knockout mice are viable and females have less visceral fat and lower total serum and high density lipoprotein cholesterol level (PubMed:15550377). Knockout mice exhibit altered lipid profile in mouse brains, compromised spatial memory and increased BACE1 activity (PubMed:27030769). Display an increase in amyloid-beta protein 42 (Abeta42) from 4 to 24 weeks of age, whereas amyloid-beta protein 40 (Abeta40) is increased at 4 weeks and decreased at 24 weeks of age (PubMed:26260791). Increased endocytotic uptake of APP into endosomes in primary microglia cells (PubMed:26260791). Reduced phagocytic uptake of Abeta42 and Abeta40 by microglia cells and phagocytes (PubMed:27472885). Decreased macrophage phagocytosis in the peritoneal cavity (PubMed:20495215). Decreased surface CD1D expression on double positive thymocytes, on antigen-presenting thymocytes, on peripheral antigen-presenting cells in the spleen and on peritoneal macrophages (PubMed:28091533). Increased accumulation of CD1D to late endosomes (PubMed:28091533). Impaired natural killer T (NKT) cell development with a 2-fold decrease in frequencies and total numbers of NKT cells in the thymus and a reduction of peripheral NKT cells in spleen and liver (PubMed:28091533). Reduced proliferation during early stages of NKT development and reduced expression of Egr2 in NKT cells (PubMed:28091533). Decreased number of plasma membrane lipid rafts on thymocytes and a reduction of CAV1 and CD1D clusters in macrophages (PubMed:28091533). RNAi-mediated knockdown reduces phagocytosis of apoptotic cells by macrophages (PubMed:16908670). {ECO:0000269|PubMed:15550377, ECO:0000269|PubMed:16908670, ECO:0000269|PubMed:20495215, ECO:0000269|PubMed:26260791, ECO:0000269|PubMed:27030769, ECO:0000269|PubMed:27472885, ECO:0000269|PubMed:28091533}. |
