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.

1576- Citrate,    Targeting citrate as a novel therapeutic strategy in cancer treatment
- Review, Var, NA
TCA↓, Citrate serves as a key metabolite in the tricarboxylic acid cycle (TCA cycle, also referred to as the Krebs cycle)
T-Cell↝, modulation of T cell differentiation
Glycolysis↓, Citrate directly suppresses both cell glycolysis and TCA.
PKM2↓, citrate also inhibits glycolysis via its indirect inhibition of PK
PFK2?, In addition, citrate can inhibit PFK2,
SDH↓, citrate can inhibit enzymes, such as succinate dehydrogenase (SDH) and pyruvate dehydrogenase (PDH), in the TCA cycle
PDH↓,
β-oxidation↓, Citrate also inhibits β-oxidation as it promotes the formation of malonyl-CoA, which decreases the mitochondrial transport of fatty acids by inhibiting carnitine palmitoyl transferase I (CPT I)
CPT1A↓,
FASN↑, citrate has a positive role in promoting fatty acid synthesis
Casp3↑,
Casp2↑,
Casp8↑,
Casp9↑,
cl‑PARP↑,
Hif1a↓, Notably, in AML cell line U937, citrate induces apoptosis in a dose- and time-dependent manner by regulating the expression of HIF-1α and its downstream target GLUT-1
GLUT1↓,
angioG↓, citrate can also inhibit angiogenesis
Ca+2↓, chelate calcium ions in tumor cells
ROS↓, The other potential mechanism involved in citrate-mediated promotion of cancer growth and proliferation may be through its ability to decrease the levels of reactive oxygen species (ROS) in tumor cells
eff↓, dual effects of citrate in tumors may depend on the concentrations of citrate treatment, and different concentrations may bring out completely opposite effects even in the same tumor.
Dose↓, citrate concentration (<5 mM) appears to boost tumor growth and expansion in lung cancer A549 cells. 10mM and higher inhibited cell growth.
eff↑, citrate combined with ultraviolet (UV) radiation caused activation of caspase-3 and -9 in tumor cells (
Mcl-1↓, citrate has also been found to downregulate Mcl-1
HK2↓, Citrate also inhibits the enzymes PFK1 and hexokinase II (HK II) in glycolysis in tumor cells
IGF-1R↓,
PTEN↑, citrate may exert its effect via activating PTEN pathway
citrate↓, In addition to prostate cancer, citrate levels are significantly decreased in blood of patients with lung, bladder, pancreas and esophagus cancers
Dose∅, daily oral administration of citrate for 7 weeks at dose of 4 g/kg/day reduces tumor growth of several xenograft tumors and increases significantly the numbers of tumor-infiltrating T cells with no significant side effects in mouse models
eff↑, combining citrate with other compounds such as celecoxib, cisplatin, and 3-bromo-pyruvate, and have generated promising results
eff↑, combination of low effective doses of 3-bromo-pyruvate (3BP) (15uM), an inhibitor of glycolysis, and citrate (3 mM) significantly depleted the proliferation capability and migratory power of the C6 glioma
eff↑, Zinc treatment could lead to citrate accumulation in malignant prostate cells, which could have therapeutic potential in clinical therapy of prostate cancer.
eff↑, synergistic efficacy mediated by citrate combined with current checkpoint blockade therapies with anti-CTLA4 and/or anti-PD1/PDL1 will develop alternative novel strategies for future immunotherapy.
