Leukocyte
TNF, tumor necrosis factor, produced by immuno competent cells, binds to TNF receptors (TNFR) and induces pro-inflammatory cytokine secretion (the NFkB pathway can be involved), increased cell migration to epidermis, activation of keratinocytes.

TNFR
TNFR
Fc

of IgG1
Etanercept is a fusion protein consisting of an extracellular part of a TNFR linked to the Fc portion of IgG1. Etanercept binds TNF & blocks its interaction with cell surface TNF receptors
Infliximab is a monoclonal antibody. It binds to
TNF, and inhibits binding of TNF to cell surface TNF
receptors
