Histological examination with H&E staining reveals markedly reduced inflammatory cell infiltration and preserved goblet cell density in TDNPs 2-treated colitic mice. Colonic tissue architecture remains largely intact compared to severe disruption in untreated animals.
Oral administration of turmeric-derived exosome-like nanovesicles with anti-inflammatory and pro-resolving bioactions for …
Wound healing assays and fecal lipocalin-2 quantification demonstrate that TDNPs 2 accelerate resolution of intestinal inflammation. Lcn-2 levels, a sensitive marker of intestinal inflammation, decrease significantly with treatment.
Oral administration of turmeric-derived exosome-like nanovesicles with anti-inflammatory and pro-resolving bioactions for …
Biocompatibility evaluation shows no significant changes in vital organ weights, pro-inflammatory cytokines, or liver function indicators in TDNPs 2-treated mice. H&E staining of major organs confirms absence of toxicity.
Oral administration of turmeric-derived exosome-like nanovesicles with anti-inflammatory and pro-resolving bioactions for …
TDNPs 2 exert their protective effect at least partly through inactivation of the NF-kB signaling pathway. Reduced phospho-NF-kB p65 expression and decreased nuclear translocation indicate suppression of this key inflammatory cascade.
Oral administration of turmeric-derived exosome-like nanovesicles with anti-inflammatory and pro-resolving bioactions for …
COX-2 protein expression is upregulated by VEGF stimulation in intestinal endothelial cells, and curcumin effectively blocks this induction. Prostaglandin E2 production follows a similar pattern of inhibition.
Curcumin inhibits VEGF-mediated angiogenesis in human intestinal microvascular endothelial cells through COX-2 …
MAPK signaling pathway activation by VEGF is attenuated by curcumin in a time- and dose-dependent manner. Phosphorylation of ERK, p38, and JNK is markedly reduced in curcumin-treated endothelial cells.

Natural product compounds shift the balance between pathogenic pro-inflammatory immune cells (right panel) and protective anti-inflammatory/immunomodulatory cell subsets (left panel). This diagram illustrates how diverse natural products can rebalance immune cell populations in autoimmune disease.
The Anti-Inflammatory and Immunomodulatory Activities of Natural Products to Control Autoimmune Inflammation.
In vivo models of autoimmune diseases have demonstrated therapeutic efficacy of various natural compounds. This figure presents preclinical evidence from animal models of rheumatoid arthritis, multiple sclerosis, or inflammatory bowel disease treated with natural products.
The Anti-Inflammatory and Immunomodulatory Activities of Natural Products to Control Autoimmune Inflammation.
Clinical translation of natural anti-inflammatory products requires understanding of bioavailability and dose-response relationships. This figure discusses the therapeutic potential and limitations of natural product-based interventions for autoimmune conditions.

TLR4/NF-kB/AP-1 signaling is a key inflammatory pathway in intestinal disease. This schematic illustrates the cascade from TLR4 receptor activation through NF-kB and AP-1 transcription factors to pro-inflammatory gene expression, and indicates where curcumin may intervene.
Curcumin and Intestinal Inflammatory Diseases: Molecular Mechanisms of Protection.
FLLL32 (a curcumin analogue) and curcumin both protect against IL-6-induced reduction of transepithelial electrical resistance (TEER) in T84 cell monolayers. This graph shows that curcumin preserves intestinal barrier integrity by counteracting cytokine-mediated tight junction disruption over 72 hours.
