Honey stimulates inflammatory cytokine production
from monocytes, Taken from a paper by A.J Tonks, R.A Cooper et
al
Clinical observations indicate that
honey may initiate or accelerate the healing of chronic wounds and
has, therefore, been claimed to have anti-inflammatory properties.
The aim of this study was to investigate the effects of honey on the
activation state of immunocompetent cells, using the monocytic
cell line, MonoMac-6 (MM6), as a model.
The effect of three honeys pasture,
manuka and jelly bush honey where investigated for the release
of important inflammatory cytokines from the MM6 cells. These
honeys, together with a sugar syrup control (artificial honey), were
incubated with MM6 cells at a concentration of 1% (w/v) for 0–24 h.
Cell culture supernatants were tested using specific assays for
tumour necrosis factor-a (TNF-a) and interleukin (IL)-1b and IL-6.
All honeys significantly increased the TNF-a, IL-1b and IL-6 release
from MM6 cells (and human monocytes) when compared with untreated
and artificial-honey-treated cells.
Jelly bush honey significantly induced the maximal release of
each cytokine compared with manuka, pasture or artificial
honeys.
These results
suggest that the effect of honey on wound healing may in part be
related to the stimulation of inflammatory cytokines from monocytic
cells. Such cell types are known to play an important role in
healing and tissue repair.
