Fig. 2From: Heparanase is the possible link between monkeypox and Covid-19: robust candidature in the mystic and present perspectiveHeparanase (HPSE) and macrophage activation: HPSE activates resting macrophage to be converted to activated macrophage with activation of cytokine receptors. HPSE via HPSE receptors increases expression of Fgr1 and NF-κB which induces expression and release of pro-inflammatory cytokines like IL-6 and IL-2. HPSE and pro-inflammatory cytokines also stimulate the activated macrophage to release more of pro-inflammatory cytokinesBack to article page
