The intratumor microbiome imbalance in pancreatic cancer promotes a tolerogenic immune response and triggers immunotherapy resistance. Here we show that Lactobacillus rhamnosus GG probiotics, outfitted with gallium-polyphenol network (LGG@Ga-poly), bolster by modulating microbiota-immune interactions. Upon oral administration, LGG@Ga-poly targets tumors specifically, selectively eradicates tumor-promoting Proteobacteria microbiota-derived lipopolysaccharides through gallium-facilitated disruption of bacterial iron respiration. This elimination microbiota impedes the activation tumoral Toll-like receptors, thus reducing immunosuppressive PD-L1 interleukin-1β expression tumor cells, diminishing immunotolerant myeloid populations, improving infiltration cytotoxic T lymphocytes tumors. Moreover, hampers growth both preventive therapeutic contexts, amplifies antitumor efficacy checkpoint blockade preclinical models female mice. Overall, offer evidence thoughtfully designed biomaterials targeting can efficaciously augment for challenging cancer.

Lipocalin-2 (LCN2) is a secreted glycoprotein linked to several physiological roles, including transporting hydrophobic ligands across cell membranes, modulating immune responses, maintaining iron homeostasis, and promoting epithelial differentiation. Although LNC2 expressed at low levels in most human tissues, it abundant aggressive subtypes of cancer, breast, pancreas, thyroid, ovarian, colon, bile duct cancers. High LCN2 have been associated with increased proliferation, angiogenesis, invasion, metastasis. Moreover, modulates the degradation, allosteric events, enzymatic activity matrix metalloprotease-9, metalloprotease that promotes tumor invasion Hence, has emerged as potential therapeutic target against many cancer types. This review summarizes relevant findings regarding expression, biological regulation LCN2, well proteins interacts cancer. We also discuss approaches targeting for treatment are currently under investigation, use interference RNAs, antibodies, gene editing.
