Ganoderma, a genus of mushrooms known for its long history medicinal use, has gained increasing attention in recent years due to potential health benefits. This review delves into the bioactive compounds found Ganoderma and elucidates intricate mechanisms underlying immunomodulatory anti-tumour activities. The diverse health-promoting effects can be attributed decadent array compounds, notably polysaccharides, triterpenoids, which play pivotal role. ability mushroom modulate immune system, enhancing activity cells, such as natural killer cells macrophages, is central focus. Furthermore, we explore how exerts through induction apoptosis, inhibition angiogenesis, interference with various signalling pathways critical cancer cell growth metastasis. As research this area continues evolve, comprehensive understanding supplement role promoting well-being emerging, offering promising avenues further investigation application healthcare.

In this study, Chinese yam polysaccharides (CYPs) were fermented using Lactobacillus plantarum M616, and changes in the chemical composition, structure, anti-inflammatory activity of CYPs before after fermentation investigated. The carbohydrate content L. M616-fermented CYP (CYP-LP) increased from 71.03% ± 2.75 to 76.28% 2.37%, whereas protein polyphenol almost unaffected compared with those unfermented (CYP-NF). monosaccharide composition CYP-NF included rhamnose, arabinose, galactose, glucose, mannose a molar ratio 0.493:0.6695:0.9738:0.7655:12.4365. CYP-LP had same monosaccharides as CYP-NF, but was 0.3237:0.3457:0.8278:2.5541:10.4995. Meanwhile, molecular weight polydispersity CYP-LP, respectively, 124.774 kDa 6.58 (CYP-NF) 376.628 17.928, indicating low homogeneity. vitro antioxidant analysis showed that M616 varying effects on against DPPH, ABTS, hydroxyl, superoxide radicals.

Cancer immunotherapy is a promising antitumor approach, whereas nontherapeutic side effects, tumor microenvironment (TME) intricacy, and low immunogenicity limit its therapeutic efficacy. In recent years, combination with other therapies has been proven to considerably increase However, achieving codelivery of the drugs site remains major challenge. Stimulus-responsive nanodelivery systems show controlled drug delivery precise release. Polysaccharides, family potential biomaterials, are widely used in development stimulus-responsive nanomedicines due their unique physicochemical properties, biocompatibility, modifiability. Here, activity polysaccharides several combined strategies (e.g., chemotherapy, photodynamic therapy, or photothermal therapy) summarized. More importantly, progress polysaccharide-based for cancer discussed, focus on construction nanomedicine, targeted delivery, release, enhanced effects. Finally, limitations application prospects this new field discussed.

Inflammatory bowel disease (IBD) is a chronic, non-specific inflammatory of the intestine that can be classified as ulcerative colitis (UC) and Crohn's (CD). Currently, incidence IBD still increasing in developing countries. However, current treatments for have limitations do not fully meet needs patients. There growing demand new, safe, highly effective alternative drugs Natural products (NPs) are used drug development treatment because their broad biological activity, low toxicity, side effects. Numerous studies shown some NPs strong therapeutic effects on IBD. In this paper, we first reviewed pathogenesis well approaches drugs.

Dendrobium officinale polysaccharide (DOP), the main active component, has a variety of bioactivities. In this study, type 2 diabetes mellitus (T2DM) and antibiotic-induced pseudo-germ-free mouse models were used to investigate hypoglycemic mechanisms DOP. The findings showed that DOP ameliorated dysfunctional glucolipid metabolism, lipopolysaccharide (LPS) leakage, metabolic inflammation levels in T2DM mice. Furthermore, significantly upregulated mRNA expression tight junction proteins Claudin-1, Occludin, ZO-1 reduced intestinal oxidative stress damage through LPS/TLR4/TRIF/NF-κB axis repair barrier. Interestingly, experiments confirmed above beneficial effects dependent on gut microbiota. 16S rRNA analysis strongly inhibited harmful bacterium Helicobacter by 94.57% facilitated proliferation probiotics Allobaculum, Bifidobacterium, Lactobacillus 34.96, 139.41, 88.95%, respectively. Therefore, is capable rebuilding certain specific microbiota restore barrier injury, which supports utilization as new prebiotic functional foods for T2DM.

Inflammatory bowel disease (IBD) is a chronic and recurrent disease. It has been observed that the incidence prevalence of IBD are increasing, which consequently raises risk developing colon cancer. Recently, regulation intestinal barrier by probiotics become an effective treatment for colitis. Akkermansia muciniphila-derived extracellular vesicles (Akk EVs) nano-vesicles contain multiple bioactive macromolecules with potential to modulate barrier. In this study, we used ultrafiltration in conjunction high-speed centrifugation extract Akk EVs. A lipopolysaccharide (LPS)-induced RAW264.7 cell model was established assess anti-inflammatory effects found EVs were able be absorbed cells significantly reduce expression nitric oxide (NO), TNF-α, IL-1β (p < 0.05). We explored preventative on colitis regulating using mouse caused dextran sulfate sodium (DSS). The findings demonstrated effectively prevented symptoms reduced colonic tissue injury. Additionally, enhanced effectiveness elevating MUC2 (0.53 ± 0.07), improving mucus integrity, reducing permeability Moreover, increased proportion beneficial bacteria Firmicutes (33.01 0.09%) downregulated harmful Proteobacteria (0.32 0.27%).
