Mesenchymal stromal cells (MSC) control excessive inflammation and create a microenvironment for tissue repair protecting from chronic inflammation and tissue fibrosis.
We examined the molecular mechanisms of MSC immunomodulatory function in mixed cultures of human adipose-derived MSC with lymphocytes.
Our data show that MSC promote unstimulated lymphocyte survival potentially by an increase in antigen presentation.
Under inflammatory conditions, mimicked by stimulation of TCR in lymphocytes, MSC suppress activation and proliferation of stimulated T cells.
Immunosuppression is accompanied by downregulation of IL-2Rα that negatively affects the survival of activated T cells.
MSC upregulate transcription of indolamine-2,3-dioxygenase (IDO) and inducible NO synthase (iNOS), which generate products negatively affecting T cell function.
Both MSC and lymphocytes dramatically increase the surface ICAM-1 level in mixed cultures.
Antibody-mediated blockage of surface ICAM-1 partially releases MSC-mediated immune suppression in vitro.
Our data suggest that MSC have cell-intrinsic molecular programs depending on the inflammatory microenvironment.
We speculate that MSC sense soluble factors and respond by surface ICAM-1 upregulation.
ICAM-1 is involved in the control of T cell activation leading to immunosuppression or modest stimulation depending on the T cell status.
Immunomodulation by MSC ranging from support of naive T cell survival to immunosuppression of activated T cells may affect the tissue microenvironment protecting from aberrant regeneration.
