Features: immunoenhancer

Mushroom Shiitake, Active hexose correlated compound
Extracted from Basidiomycete mushrooms (eg, shiitake [Lentinula edodes]) that is purported to improve immune function.
Summary:
- Can significantly inhibit carcinogenesis and improve anti-tumor effects, thus increasing the effectiveness of cancer immunotherapy.
- Enhanced abundance of Akkermansia in the intestine of those who responded positively to the ICI(immune checkpoint inhibitors).

-Eat fermented foods then fibre to maintain them. Fruits and vegs for fibre Chicory root for fibre (inulin which is main prebiotic)

AHCC is mainly derived from the mycelium of Shiitake mushrooms.
• It is rich in polysaccharides that are believed to enhance immune function.
• The compound may influence various pathways in cancer, including boosting NK cell activity, modulating cytokine production, influencing the NF-kB inflammatory pathway, and reducing oxidative stress.

Pathways:
-Stimulate cytokine production (e.g., interleukins, tumor necrosis factor) and enhance the function of macrophages and dendritic cells.

Component class	Specific compound / fraction	Typical source within shiitake	Main structural type	Approximate amount	Main relevance	Notes
Beta-glucan	Lentinan	Fruiting body cell wall; enriched by hot-water extraction	β-(1→3) backbone with β-(1→6) branches; often triple-helix in active preparations	About 4.1–5.5 mg/g dry weight in one quantified fruiting-body study; broader practical range often cited around 0.4–1.3% of dry weight	Best-known shiitake anticancer / immunomodulatory beta-glucan	This is the main named shiitake β-glucan. Amount varies a lot with strain, storage, and assay method.
Beta-glucan	Total β-glucans	Whole fruiting body, especially cap and stem cell walls	Mixed fungal β-glucan pool, mostly β-linked wall glucans	Pileus about 20.1–44.2% dry matter; stipe about 29.7–56.5% dry matter across cultivars	Broad immune, fiber, and functional-food relevance	Total β-glucan is much higher than lentinan alone. “Total β-glucan” should not be confused with lentinan content.
Beta-glucan	β-(1→3),(1→6)-glucan fraction	Purified polysaccharide fraction from shiitake	Branched fungal β-glucan	Usually reported as an isolated fraction rather than a fixed natural percentage	Most likely to carry the classic lentinan-like immune activity	This is the dominant medicinally relevant shiitake β-glucan architecture.
Beta-glucan	β-(1→6)-glucan fraction	Minor purified glucan fraction	More linear / differently linked β-glucan fraction	No reliable simple whole-mushroom percentage found	Possible supportive bioactivity	Reported in fractionation studies, but less emphasized than the β-(1→3),(1→6) fraction.
Alpha-glucan	α-(1→3)-glucan fraction	Cell-wall associated polysaccharide fraction	α-glucan	No simple whole-mushroom percentage established here	Structural / possible adjunct bioactivity	Important because shiitake contains more than just β-glucans.
Low-molecular-weight bioactive	Eritadenine	Free small molecule in caps, stems, and mycelium	Purine-like alkaloid / adenine derivative	Commonly reported around 50–70 mg/100 g dry weight in caps and 30–40 mg/100 g dry weight in stems; some reports are much higher depending on method	Best known for cholesterol-lowering and methylation-related metabolic effects	Not a glucan. Often listed among the major distinctive shiitake actives.
Sterol	Ergosterol	Membrane sterol in fruiting body tissues	Fungal sterol; vitamin D2 precursor	Examples around 294–478 mg/100 g dry weight; other reports extend into the low mg/g dry-weight range	Nutritional relevance; precursor for UV-generated vitamin D2	Not a β-glucan, but one of the main recognized shiitake actives.
Organosulfur precursor	Lentinic acid	Present in dried shiitake; precursor pool changes with drying / rehydration	Sulfur-containing flavor precursor	Highly process-dependent; no single stable food-table value	Precursor to aroma compounds and possible ancillary bioactivity	Main importance is as precursor to lenthionine during processing and rehydration.
Organosulfur volatile	Lenthionine	Generated during drying / rehydration / processing from lentinic acid	Cyclic organosulfur volatile	One induced-cultivation study reported about 88.2 μg/g at peak conditions	Characteristic shiitake aroma; possible antimicrobial / bioactive relevance	More important as a flavor-signature compound than as the main medicinal constituent.
Phenolics / other metabolites	Phenolics, terpenoids, sterols, peptides	Distributed through fruiting body and extracts	Mixed secondary-metabolite pool	Usually reported as extract-dependent totals rather than stable whole-mushroom values	Antioxidant, anti-inflammatory, and supportive nutraceutical effects	Real but less standardized than lentinan, eritadenine, and ergosterol.

Type: white blood cell

T cells are white blood cells that play a central role in the adaptive immune response.
Subsets and Function:
Cytotoxic T Cells (CD8+): Recognize and kill infected or malignant cells.
Helper T Cells (CD4+): Assist in orchestrating the immune response by secreting cytokines and supporting the functions of other immune cells.
T cells, particularly CD8+ cytotoxic T cells, can recognize tumor antigens presented on major histocompatibility complex (MHC) molecules and directly kill malignant cells.
Regulatory T Cells (Tregs): Maintain immune tolerance and prevent autoimmunity but may also suppress anti-tumor responses in the tumor microenvironment.
Tumor-Infiltrating Lymphocytes (TILs):
Tumor Microenvironment:
The presence of T cells within tumors, often referred to as tumor-infiltrating lymphocytes, is a key indicator of an ongoing anti-tumor immune response.
Regulatory T Cells (Tregs):
Tregs within the tumor environment may inhibit the activity of cytotoxic T cells through the secretion of immunosuppressive cytokines (e.g., IL-10, TGF-β), thus allowing tumors to evade the immune response.

In many cancers, a robust T cell infiltrate is correlated with a better overall survival, lower rates of relapse, and improved responses to therapy.
Assessing the type, density, and activation state of T cells in the tumor microenvironment can provide valuable prognostic information. High levels of active, cytotoxic T cells generally indicate a better prognosis.
