Anti-IL-6

Anti-interleukin-6 agents are a class of therapeutics. Interleukin 6 is a cytokine relevant to many inflammatory diseases and many cancers.[1] Hence, anti-IL6 agents have been sought.[2][3][4][5][6] In rheumatoid arthritis they can help patients unresponsive to TNF.[7]

The first approved medication in this class, tocilizumab (Actemra), is an antibody directed against the IL6-receptor.[8] The second, siltuximab (Sylvant), is directed against IL-6 itself.[1][9]

Several agents are in clinical trials: sarilumab,[10] olokizumab (CDP6038)[11][12] elsilimomab, BMS-945429(ALD518), sirukumab (CNTO 136), and CPSI-2364 an apparent macrophage-specific inhibitor of the p38 mitogen-activated protein kinase pathway.[13] ALX-0061.[7]:Table1

eg. for rheumatoid arthritis : clazakizumab, olokizumab, sarilumab and sirukumab have all reported encouraging phase 2 results.[7] Sirukumab is in multiple phase 3 trials.[7]:Table1

Agents in pre-clinical development include ARGX-109,[14][15] FE301,[1] FM101[16]

Exercise induced IL-6 may be beneficial

New research has found IL-6 to be an anti-inflammatory cytokine with multiple beneficial effects when released by contracting muscle as a myokine. IL-6 had previously been classified as a proinflammatory cytokine. Therefore, it was first thought that the exercise-induced IL-6 response was related to muscle damage.[17] However, it has become evident that eccentric exercises are not associated with a larger increase in plasma IL-6 than exercise involving concentric “nondamaging” muscle contractions. This finding demonstrates that muscle damage is not required to provoke an increase in plasma IL-6 during exercise. In fact, eccentric exercise may result in a delayed peak and a much slower decrease of plasma IL-6 during recovery.[18] Anti-IL-6 therapies should therefore take into consideration the (beneficial) anti-inflammatory effects of myokines generally, including the now-established multiple benefits of muscle-derived Interleukin 6.[18]

Food and diet

It has been reported that lunasin, a soy peptide, reduces inflammation by reducing interleukin 6 and may help in leukemia[vague].[19]

Luteolin reduces IL-6 production in some neurons.[20]
