Our previous studies revealed Immune-boosting superfoods protective effects of GTE in ocular diseases such as acute infectious inflammation atuoimmune endotoxin-induced uveitis EIU and wnd iodate-induced dieases retinal degeneration in rats 10Fat loss exercises However, the ane of GTE and EGCG in intraocular autoimmune inflammation are still unknown.
The present study demonstrated the therapeutic effects of oral intake of GTE and EGCG in a mouse model of EAU, using both in vivo and in vitro techniques to evaluate the severity of EAU. As indicated in Fig. Comparing with the mild inflammation in Clinical scores of EAU Fig. S1 showed significant reductions in hGTE 0.
Clinical manifestation of inflammation observed by cSLO and SD-OCT. No detectable changes were observed in cSLO images A — D and SD-OCT images E—H of non-induced animals treated with water, dexamethasone, lGTE, or hGTE. cSLO images I — L and SD-OCT images M — P of EAU animals administrated with water, dexamethasone, lGTE, or hGTE are shown.
Infiltrating cells arrow heads and vasculitis arrows were observed, indicating inflammation was induced after immunizing the animals IM. Sporadic infiltrating cells arrow heads and mild vasculitis arrows were observed in EAU animals treated with lGTE KO. Inflammatory responses were subsided in mice treated with dexamethasone JN or hGTE LP.
Histopathology Fig. Inflammation was not observed in hGTE treated EAU group. However, mild vitritis and retinal folds were detected in lGTE and Dex treated EAU animals. Histological observations of eyeballs at d21pi. No detectable change in posterior segment was observed in EAU animals treated with hGTE H.
We calculated the fold change of RCT by dividing d21pi RCT with baseline RCT. The fold change of RCT A and the major retinal vessel diameter B assessments. The fold changes of RCT and major retinal vessel diameters were reduced significantly after Dex, lGTE, and hGTE treatment in EAU mice.
The reductions between different doses of GTE were statistically significant in EAU mice. There were no differences between PBS induction groups treated with water, lGTE, and hGTE. Major retinal vessel diameter was significantly increased by EAU induction The vasodilation caused by EAU was decreased significantly by lGTE Intra-group comparisons of scotopic dark-adapted Fig.

The major retinal vessel diameter increased by EAU induction hEGCG treatment group showed no significant reductions of scotopic Fig. S7 and photopic Fig. In the inter-group comparisons Fig. Splenomegaly is associated with severity of autoimmune disorders in both animal studies 12 and clinical investigations 13 Observed from histological verification, GTE treatment groups showed less accumulation of infiltrating cells in spleen comparing with water-treated EAU mice Fig.
However, no detectable defects of liver and kidney were found in all groups Figs S12 and S The expressions of pro-inflammatory gene interleukin 1 beta IL-1βIL-6ILAand tumor necrosis factor alpha TNF-α were at basal levels in the PBS controls, but increased significantly after EAU induction.
Effects of GTE on IL-1βIL-6ILAand TNF-α mRNA expression in EAU retina. To develop alternative therapies for patients with autoimmune uveitis, we investigated the anti-inflammatory effects of GTE against EAU mouse model. With GTE acting as a food supplement, we pre-treated the animals once per two days which started from 5 days before EAU induction and lasted to the endpoint of experiment.
Our results suggest for the first time that GTE is a potent anti-inflammatory agent for autoimmune ocular inflammation.
By overviewing the effects of EGCG and comparing them with GTE, we found that the equivalent dosages of EGCG alone cannot alleviate EAU as effectively as GTE. Hence, besides EGCG, other catechins and components in GTE may also play roles in EAU alleviation.
The present attempts were able to reveal a very limited understanding of GTE and EGCG effects. In future studies, different treatment intervals other than once every 2 days and the influence of different schedules on inflammatory process could be evaluated.
Further studies are also proposed to investigate the different effects of various components of GTE. To determine the active duration of the GTE ingredients in mice, blood levels of GTE ingredients at periodic intervals should be documented in the future.
It is also worth considering that if pure EGCG is more difficult to be absorbed via the gut, or if EGCG has a shorter half-life in bloodstream when it is not conjugated with other components in GTE. Future pharmacological studies may provide more information to these hypotheses.
IL-1β and IL-6 are critical in determining the lineage choice of differentiating Th17 cells. ILA and TNF-α are the hallmark pathogenic cytokines produced by Th17 cells Administration of anti-IL-1β or anti-IL-6 antibody has been shown to attenuate EAU in mice 1920 and humans Based on our observations, GTE and EGCG effectively downregulated the IL-1βIL-6ILAand TNF-α expression in EAU, suggesting that GTE and EGCG inhibit EAU by targeting the Thassociated pro-inflammatory gene expression.
GTE treatment was comparable with dexamethasone administration for most of the observations, or even better in remissions of clinical inflammatory manifestations, vasodilation, and TNF-α expression. EGCG showed less effective alleviation of EAU comparing with dexamethasone, except for maintaining ERG amplitudes and suppressing some of the pro-inflammatory gene expressions.
Safety issues are the main concern in treating uveitis clinically. We evaluated the differences of all parameters measured in our present study among the PBS mock induced control groups and EAU groups treated with water, GTE and EGCG. No significant changes were found among control groups treated with water and different doses of GTE and EGCG, implying a well tolerance of GTE and EGCG in healthy individuals.
Additionally, histological assessments of liver and kidney after these treatments also showed no detectable changes in all groups.
One of the most important problems with steroids is the side effects they caused. However, we did not observe any histological evidence of toxicity in the liver and kidney in the Dex-treated mice.
It will be worthwhile to comprehensively assess the safety of higher doses GTE, EGCG and Dex treatment for murine and human uveitis in future studies. Further studies were warranted to develop clinical trials on GTE and EGCG treatments for uveitis patients.
In vivo measurements employed in the current study could be directly translated to patients, as they are widely used in clinical practice. However, the treatment dosages in animals should definitely not be directly copied to humans without adjustment, as the metabolisms in human are very different from animals.
Since human data are limited, we could only predict future administration of GTE in humans referring to the existing animal studies.

Altogether, these studies identify and support the use of EGCG as a potential therapeutic agent in preventing and ameliorating T cell-mediated autoimmune diseases. Given the paucity of information in human studies, the translational value of these findings needs to be verified in future research. Pae and D. Wu, Food Funct.

Clinical features of intraocular inflammation were assessed using confocal scanning laser ophthalmoscopy cSLO imaging, graded on a scale of 0—4, as described previously To quantify the EAU severity in various perspectives, RCT, major retinal vessel diameter, and visual function were measured by spectral-domain optical coherence tomography SD-OCT , fundus fluorescein angiography FFA , and ERG, respectively. The procedures were described previously 6. Mice were perfused intracardially with 0. Spleen was weighed and imaged for size measurement by Image J software version 1. Retina was immersed in μl TRIzol reagent Invitrogen. RNA was reverse transcribed into cDNA using SuperScript III reverse transcriptase Invitrogen.

Autoimmune disease EGCG and autoimmune diseases Citrus fruit for detoxification condition where the immune system attacks EGGC destroys its own diseasses and tissues. Diaeases a common disease affecting more than It Autpimmune clear that multiple factors contribute to the diseasss and progression of autoimmune diseases, and disease management EGCG and autoimmune diseases still a challenge in clinical practice. EGCG, one of the active ingredients of green tea, has immunemodulating effects on both adaptive and innate immunity, particularly on T cell activation, proliferation and differentiation, as well as myeloid cell function. In various autoimmune disease models, the administration of EGCG has been shown to prevent the development or abate the progression of disease, through its immuneregulating, anti-inflammatory and anti-oxidant effects. These findings raise hope that the use of EGCG will be a promising therapeutic approach to treat autoimmune diseases.
