Effect of Plasma-Derived Exosomes of Refractory/Relapsed or
Responsive Patients with Diffuse Large B-Cell Lymphoma on
Natural Killer Cells Functions
The purpose of this study was to investigate effect of plasma-derived exosomes of refractory/relapsed or responsive diffuse large B-cell lymphoma (DLBCL) patients on natural killer (NK) cell functions.
Materials and Methods
In this cross-sectional and experimental study, NK cells were purified from responsive patients
(n=10) or refractory/relapsed patients (n=12) and healthy donors (n=12). NK cells were treated with plasma-derived
exosomes of responsive or refractory/relapsed patients. We examined the expression levels of
We observed an increased level of
Our findings demonstrated adverse effect of plasma-derived exosomes of DLBCL patients on some functions of NK cell. It was also determined that low NK cell count might be associated with impaired response to R-CHOP and an increased recurrence risk of cancer.
