By mechanisms yet to be clearly identified, the two LX's also: a) stimulate the bacteria-killing capacity of leukocytes and airway epithelial cells; b) block production of the pro-inflammatory cytokine, TNFα, while increasing production of the anti-inflammatory cytokine, CCR5 by T lymphocytes; c)' enhance the ability of monocytes and macrophages to phagocytos (i.e. ingest) and thereby remove potentially injurious apoptotic neutrophils and eosinophils from inflammatory sites (see Efferocytosis) either by direct effecting these cells or by stimulating NK cells to do so; d) cause various cell types to reduce production of pro-inflammatory reactive oxygen species and expression of Cell adhesion molecules and increase production of the platelet inhibitor, PGI2 and the vasodilator, nitric oxide; e) inhibit production of pro-inflammatory cytokines by mesangial cells, fibroblasts, and other pro-inflammatory cell types; and f) reduce perception of pain due to inflammation.
