 Interleukin-10 Is a Mesangial Cell Growth Factor In Vitro and In Vivo   (Site not responding. Last check: 2007-10-09)
As macrophages are known to produce interleukin-10 (IL-10), we investigated the effect of recombinant murine IL-10 (rIL-10) on mesangial cell growth.
These cells exhibited a dose-dependent proliferative response to rIL-10 (23 % to 70 % at 80 ng/mL; p < 0.01), as assessed by both 3H thymidine uptake and cell count.
Rat mesangial cells were also shown to express IL-10 mRNA and protein, as determined by Northern blotting and immunostaining, thereby suggesting a role for IL-10 in autocrine mesangial cell growth.

 Effect of vitamin D and matrix metalloproteinases on mesangial cell phenotype
Recent data suggests that 1,25-(OH)2D3 blocks dendritic cell maturation influencing the development of regulatory T cells.
Further, we hypothesize that 1,25-(OH)2D3 may alter the balance of matrix deposition and removal in mesangial cells by altering MMP expression.
Primary rat masangial cells will be isolated, placed in culture in the presence or absence of 1,25-(OH)2D3 and subjected to mechanical stretch (stress).
