Disease relevance of MARCO

 

High impact information on MARCO

  • Transfection of COS cells with MARCO cDNA conferred mAb-inhibitable TiO2 binding [5].
  • Marco Baggiolini and Clemens Dahinden discuss the involvement of CC chemokines in the recruitment and activation of the main effector cells of allergic inflammation [6].
  • The purpose of this study was to isolate which SRs (macrophage receptor with collagenous structure (MARCO), CD204, or CD36) were involved using a variety of SR single and double null mice [4].
  • Similar to the results with C57BL/6 AM, MARCO was involved with silica-induced cell death in the 129/SvJ strain [4].
  • Transfection of Chinese hamster ovary cells with human MARCO supported these conclusions, as silica particles bound to and initiated apoptosis in the MARCO-transfected cells [4].
 

Chemical compound and disease context of MARCO

  • A Phage Display Screen and Binding Studies with Acetylated Low Density Lipoprotein Provide Evidence for the Importance of the Scavenger Receptor Cysteine-rich (SRCR) Domain in the Ligand-binding Function of MARCO [7].
 

Biological context of MARCO

  • Although the transfection experiments with transmembrane MARCO variants have indicated a crucial role for this domain in bacterial binding, the monomeric domain exhibited low, barely detectable bacteria-binding activity [1].
  • The objective of this study was to test the expression of 3 macrophage scavenger receptors (SRs) that are responsible for innate immunity against gram-negative bacteria: SR class A type I (SR-AI), SR-AII, and the macrophage receptor with collagenous structure (MARCO) [2].
  • BACKGROUND: Phagocytosis of unopsonized pollutant particles by alveolar macrophages (AM) occurs via the macrophage receptor with collagenous structure (MARCO) [8].
  • The results indicate that expression of MARCO has a direct effect in generating the phenotype of activated macrophages necessary for the trapping and removal of pathogens and other foreign substances [9].
  • In this study, we show that ectopic expression of MARCO in cell lines such as Chinese hamster ovary, HeLa, NIH3T3, and 293 induces dramatic cell shape changes [9].
 

Anatomical context of MARCO

 

Associations of MARCO with chemical compounds

  • However, the human MARCO polypeptide chain lacked the intracellular cysteine present in mouse, as well as two extracellular cysteines that form interchain disulfide bonds in the murine protein [3].
  • Using the surface plasmon resonance technique, we show here that a recombinant, soluble form of MARCO, sMARCO, binds the major Gram-negative and -positive bacterial surface components, lipopolysaccharide and lipoteichoic acid [7].
  • Yet, the interaction of these two polyanions with sMARCO is of much lower affinity than that of polyinosinic acid, a polyanionic inhibitor of bacterial binding to MARCO [7].
  • Phosphorothioate (PS)-linked CpG-ODN stimulated IL-12 and NO production in wild-type but not in MARCO-deficient, thioglycollate-elicited peritoneal macrophages [11].
  • The MARCO (macrophage receptor with collagenous structure) glycoprotein belongs to the scavenger receptor type family of pattern-recognition molecules produced by a subset of marginal zone macrophages in the spleen [12].
 

Other interactions of MARCO

  • Our findings suggest that UGRP1-MARCO is a ligand-receptor pair that is probably involved in inflammation and pathogen clearance in the lung [13].
  • In marked contrast, MARCO expression was high in almost all samples of RA SFMC [2].
  • Cytocentrifuged AM were dual immunostained with monoclonal antibodies to the panmacrophage marker CD68, and either MARCO or an appropriate isotypic control [8].
  • The ability of MARCO to bind CpG-ODNs and conversely, to costimulate IL-12 and NO production upon specific ligation with immobilized mAb is consistent with MARCO being a signaling receptor for CpG-ODNs, costimulating TLR9-mediated NO and IL-12 production in macrophages [11].
  • According to Kaplan-Meier estimates, high EPHA1, and low SMAD1 and MARCO expression were associated with better progression-free survival (PFS) [14].
 

Analytical, diagnostic and therapeutic context of MARCO

  • Using COS transfectants with different truncated forms of MARCO, allowed epitope mapping for the PLK-1 Ab to MARCO domain V between amino acid residues 420 and 431 [10].
  • A polyclonal antibody to human MARCO identified the expected approximately 70-kD band on Western blots of lysates of normal bronchoalveolar lavage (BAL) cells (>90% AMs) and showed strong immunolabeling of human AMs in BAL cytocentrifuge preparations and within lung tissue specimens [5].
  • Radiation hybrid mapping localized hMARCO to chromosome 2q14 [15].

  • The electrophysiological parameters (Marco EMG amplitudes and fiber density) revealed evidence of reinnervation, indicating preceeding denervation and therefore loss of motor units [17].
