Mycoplasma receptor

Figure 7. The summary of systems involved in (or related to) the uptake and assimilation of iron represents a schematic view of a typical Gram-negative bacterium. The OM receptors, as well as the proteins of the Ton complex, are not present in Gram-positive bacteria, and were not found in mycobacteria and members of the mycoplasma group...

LDL transports cholesterol to most extrahepatic parenchymal cells [121]. In contrast, the adrenal gland, ovary and testis utilise HDL cholesterol [122]. Studies in vitro show that LDL uptake is mediated by high-affinity receptor binding of the lipoprotein, subsequent endocytosis and catabolism [123]. However, other studies show that a significant portion of free cholesterol in serum lipoproteins can be transferred to the mycoplasma cell membrane by simple exchange [123,124]. A similar process may occur in eucaryotic cells [94].

The nature of mycoplasma receptor sites on erythrocytes or other mammalian cells has not been extensively investigated. Of seventeen mycoplasma serotypes investigated, four bind to putative sialic acid receptors (Manchee and Taylor-Robinson, 1969). Mycoplasma pneumoniae and Mycoplasma gallisepticum appear to attach to sialic acid receptors on the erythrocytes or tracheal epithelial cells. Pretreatment of...
