Miller et al., Brain Behav Immun 2003
(Body Weight...) :
Structural equation modeling yielded support for a model in which depressive symptoms promote weight accumulation, which in turn activates an inflammatory response through two distinct pathways : expanded adipose tissue release of interleukin-6 and
leptin induced upregulation of
interleukin-6 release by white blood cells ( CFI =.99 ; NNFI =.99 ; RMSEA =.05 )
Fukuda et al., Fertil Steril 2003

leptin induced tumor necrosis factor-alpha,
interleukin-6 , and interleukin-10 production by PBMCs of patients in an acute phase of disease but not in patients in a stable phase or in healthy controls
Trujillo et al., J Clin Endocrinol Metab 2004
:
Interleukin-6 regulates human adipose tissue lipid metabolism and
leptin production in vitro ... We used adipose tissue organ culture to test the direct
effects of
IL-6 on
leptin expression, lipolysis, and lipoprotein lipase activity ... Although IL-6 had no significant effects under basal conditions, culture with the combination of IL-6 and dex, compared with dex alone, for 2 d increased leptin in both depots [ +95 +/- 30 % ( sc ) and +67 +/- 19 % ( Om ), P < 0.01 ] ;
IL-6 did not
affect leptin production when added in the presence of insulin
Stanley et al., J Bone Miner Res 2006

We sought to determine whether
osteoblasts (OBs) can serve as accessory cells (ACs) for T-cell activation and whether T cells directly
activate OB production of
IL-6 , using primary human OBs ( NHOst ), the transformed fetal osteoblast line hFOB1.19, and an osteosarcoma line SaOS-2
Fenton et al., Carcinogenesis 2006

Interleukin-6 production
induced by
leptin treatment promotes cell proliferation in an Apc ( Min/+ ) colon epithelial cell line ... Here we show, for the first time, that
leptin induces elevated
IL-6 production in IMCE cells but not in YAMC cells ... Further, we elucidate a novel mechanism by which
leptin activates TACE/ADAM17 associated IL-6R shedding and
trans-IL-6 signaling in IMCE by induction of IL-6 production ... These data implicate
leptin induced
IL-6 production, signaling and subsequent STAT3 activation as early events promoting the survival/proliferation of colon epithelial preneoplastic cells

Tang et al., J Immunol 2007
:
Leptin induced
IL-6 production is mediated by leptin receptor, insulin receptor substrate-1, phosphatidylinositol 3-kinase, Akt, NF-kappaB, and p300 pathway in microglia ...
Leptin caused concentration- and time dependent increases in
IL-6 production ... Our results suggest that
leptin increased
IL-6 production in microglia via the leptin receptor/IRS-1/PI3K/Akt/NF-kappaB and p300 signaling pathway ...
Leptin mediated
IL-6 production was attenuated by OBRl receptor antisense oligonucleotide, PI3K inhibitor ( Ly294002 and wortmannin ), Akt inhibitor ( 1L-6-hydroxymethyl-chiro-inositol-2- ( ( R ) -2-O-methyl-3-O-octadecylcarbonate ) ), NF-kappaB inhibitor ( pyrrolidine dithiocarbamate ), IkappaB protease inhibitor ( L-1-tosylamido-2-phenylenylethyl chloromethyl ketone ), IkappaBalpha phosphorylation inhibitor ( Bay 117082 ), or NF-kappaB inhibitor peptide

(Disease Models, Animal...) :
Under serum-free conditions, adiponectin ( 1 mug/ml ) inhibited
leptin induced autocrine
IL-6 production, soluble IL-6 receptor shedding, trans-IL-6 signaling and subsequent STAT3 phosphorylation in IMCE cells ... These data indicate that adiponectin acts on preneoplastic colon epithelial cells to regulate cell growth via 2 distinct pathways inhibiting
leptin induced NF-kappaB dependent autocrine IL-6 production and
trans-IL-6 signaling

Vuolteenaho et al., Mediators Inflamm 2009
(Inflammation...) :
Interestingly, inhibition of leptin induced NO production with a selective iNOS inhibitor 1400 W inhibited also the production of IL-6, IL-8, and PGE ( 2 ), and this was reversed by exogenously added NO-donor SNAP, suggesting that the
effects of
leptin on
IL-6 , IL-8, and PGE ( 2 ) production are dependent on NO
Orlova et al., Bull Exp Biol Med 2009

IL-6 production
Granowitz et al., Biochem Biophys Res Commun 1997

When considered in the context of animal studies showing that
interleukin-1 and tumor necrosis factor-alpha

(Critical Illness...) :
The negative relation between IL-6 and leptin is of potential importance, as high
IL-6 levels have been associated with poor outcome in critically ill patients, and relatively low
leptin levels may
impair sympathetic system and immune functions
