The interleukin 2 CD28-responsive complex contains at least three members of the NF kappa B family: c-Rel, p50, and p65
PMID:15079071
when T cells were stimulated with anti-CD3 antibody, RelA, c-Rel, and p50 were preferentially recruited to the IL-2 promoter
PMID:14668329
predominance of p50-p50 homodimers binding to the IL-2 promoter ??B site in tolerant T cells CD4+ correlated with repression of NF??B-driven transcription.

Signal-dependent nuclear translocation of p50 and p65 is impaired in PKC?????/??? cells.
PMID:20138012
NF-??B heterodimer (RelA-p50) translocates to the nucleus, where it activates the transcription of its target genes ( Karin and Ben-Neriah, 2000 and Pereira and Oakley, 2008). Nuclear p65 staining was detected in the stroma of HPV skin sections but not in the skin of nontransgenic control mice
PMID:23430059
PMID:19171876, PMID:17145890
NFkB p50/p50 homodimers (which lack the transactivation
domain) compete with canonical p65/p50 heterodimers for
the binding sites on the inflammatory
gene promoters, thereby blocking p65/p50 promoter
binding and gene transcription.
p50 NF-kappaB overexpression accounts for the
inability of tumor assasiated macrophages to mount
an effective M1 antitumor response capable of inhibiting tumor growth.

CSF1 downregulates TNF, IL-23p19, IL-12p40 expression probably via induction of acomulation of p50 homodimer and inhibition of p65/p50 NF-kB signaling.

CSF2 upregulates expression of TNF, and have positive influence on IL12p70 (p40+p35), IL23 (p40+p19) expression, probably via induction rapid IkBa degradetion, RELA nuclear translocation and formation p65/p50 heterodimers provided induction of NFkB signaling.

Increased TNF expression downstream of HMGB1 is regulated via MYD88 and probably NFkB.
PMID:10754326
Human TNF-alpha gene has binding sites for NF-kappa B. By transient transfection,
NF-kappa B p65 and p50 synergistically activated the TNF-alpha promoter.
Although both the kappa B1 and kappa B3 sites bound transcriptionally active NF-kappa B p50/p65 heterodimers, only the kappa B1 site contributed to down-regulation by NF-kappa B p50 homodimers.
