In THP-1 cells , Fc gamma R cross-linking induced NF-kappa B , which is known to bind to the regulatory region of the long terminal repeat ( LTR ) of HIV-1 and to activate HIV-1 transcription . Anti-TNF-alpha antibody but not anti-IL-1 beta antibody strongly inhibited both the induction of HIV-1 - LTR -driven transcription and the induction of NF-kappa B by Fc gamma R cross-linking .
