The basis of the MAT is that pyrogens, via Toll-like receptors (TLRs) expressed on monocytes, stimulate cytokine production. Here, we report that, at concentrations that did not induce whole blood cytokine production when tested separately, (1\u21923)-\u03b2-D-glucans powerfully co-stimulated cytokine production (IL-6\/IL-8) induced by ligands for TLR1\/2, TLR2\/6, TLR4, and TLR5. Experiments were performed to investigate the involvement of particular (1\u21923)-\u03b2-D-glucan receptors such as dectin-1. Spleen tyrosine kinase (Syk) inhibition attenuated the potentiating effects of (1\u21923)-\u03b2-D-glucans on TLR-induced cytokine production, suggesting that dectin-1 was involved. However, experiments with low molecular (1\u21923)-\u03b2-D-glucans such as laminarin argued against the involvement of dectin-1 in the co-stimulatory effects of (1\u21923)-\u03b2-D-glucans. Thus, although the receptors involved in the co-stimulatory actions of (1\u21923)-\u03b2-D-glucans on TLR-induced cytokine production are yet to be elucidated, it is clear that (1\u21923)-\u03b2-D-glucans may greatly affect MAT results and, when undetected in pharmaceuticals, may give rise to serious side-effects in patients co-exposed to other elicitors of innate immunity, such as during infections.
