Disease relevance of CAMP

 

Psychiatry related information on CAMP

 

High impact information on CAMP

  • Here, we describe the production and function of the cathelicidin antimicrobial peptides LL-37, its precursor hCAP-18 and its ortholog CRAMP in epithelial cells of human and mouse urinary tract, respectively [10].
  • In addition, clinical E. coli strains that were more resistant to LL-37 caused more severe urinary tract infections than did susceptible strains [10].
  • The mature human (LL-37) and mouse (CRAMP) peptides are encoded by similar genes (CAMP and Cnlp, respectively), and have similar alpha-helical structures, spectra of antimicrobial activity and tissue distribution [11].
  • Moreover, erythrocytes coated with supernatant antigens from the Camp or FCR-3 strain were invaded normally by merozoites of the homologous strain but were partially resistant to invasion by merozoites of the heterologous strain [12].
  • IL-4/IL-13 enhanced VV replication while downregulating LL-37 in VV-stimulated keratinocytes [13].
 

Chemical compound and disease context of CAMP

 

Biological context of CAMP

  • Taken together, these findings demonstrate that LL-37/hCAP-18 is a multifunctional antimicrobial peptide with a central role in innate immunity by linking host defense and inflammation with angiogenesis and arteriogenesis [1].
  • Of note, LL-37 dose dependently (0.01-5 microg/ml) suppressed neutrophil apoptosis, accompanied with the phosphorylation of ERK-1/2, expression of Bcl-x(L) (an antiapoptotic protein), and inhibition of caspase 3 activity [3].
  • Transfection of this active form, ASK1-DeltaN, significantly enhanced the expression of hBD1-3 and LL37 [19].
  • Increased levels of inflammatory markers in bronchoalveolar lavage fluid were associated with elevated concentrations of LL-37/hCAP-18 (total cell count, P = 0.006; relative neutrophil count, P = 0.002) [20].
  • Deterioration of lung function, measured by MEF25 (maximal flow rate at 25% of residual forced vital capacity), correlated with decreased hBD-2 (P = 0.026), but increased LL-37/hCAP-18 concentrations (P = 0.016) [20].

Other interactions of CAMP

  • Here we report that LL-37 is chemotactic for, and can induce Ca(2+) mobilization in, human monocytes and formyl peptide receptor-like 1 (FPRL1)-transfected human embryonic kidney 293 cells [21].
  • Pulmonary or systemic infections were associated with significantly increased concentrations of LL-37, hBD-1, and hBD-2 [31].
  • Among the bacteria tested in this study, F. nucleatum was highly susceptible to hBD3 and LL37, and S. mutans was highly susceptible to hBD3 [32].
  • CAP18 and PAI-1 negatively correlated with pulmonary function [33].
  • However, we found that hCAP18 and GPI-PLD, along with apoA-I, are common components of both lytic and non-lytic primate HDLs [34].
