Targeting peripheral blood pro-inflammatory CD28null T cells and natural killer T-like cells by inhibiting CD137 expression: possible relevance to treatment of bronchiolitis obliterans syndrome.
J Heart Lung Transplant. 2013 Nov; 32(11):1081-9.JH

Abstract

BACKGROUND

We have shown that bronchiolitis obliterans syndrome (BOS) is associated with attenuated suppression of pro-inflammatory cytokines and granzyme B by steroid-resistant peripheral blood CD28nullCD137+ T cells and natural killer T (NKT)-like cells. We hypothesized that we could target these steroid-resistant lymphocytes by inhibiting costimulation through CD137.

METHODS

Isolated peripheral blood mononuclear cells from transplant patients with stable lung function, patients with BOS, and healthy controls were stimulated with anti-CD3 with and without blocking anti-CD137 and with and without 10(-6) mol/liter methylprednisolone (MP) (with and without stimulatory anti-CD137). Pro-inflammatory cytokine profiles and expression of the cytotoxic mediator, granzyme B, by CD28null T and NKT-like cells were determined using flow cytometry.

RESULTS

There was a significant decrease in the percentage of CD28null T and NKT-like cells producing interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and granzyme B in all individuals in the presence of anti-CD137 blocking antibody compared with anti-CD3 alone (eg, 30% decrease in CD8+CD28null TNF-α+ cells). Stimulatory anti-CD137 was associated with an increase in pro-inflammatory/cytotoxic cells. Treatment with anti-CD137 blocking with prednisolone further reduced IFN-γ, TNF-α, and granzyme B in these cells.

CONCLUSIONS

Blocking CD137 expression in CD28null T cells and NKT-like cells is associated with down-regulation of IFN-γ, TNF-α, and granzyme B. Targeting CD137 reduces pro-inflammatory/cytotoxic expression in steroid-resistant CD28null T and NKT-like cells and may have therapeutic implications for patients with BOS.
