Lactate

Recent Findings on lactate

Lactate Signaling in Disease: Lactate accumulation couples glycolysis to immunosuppression, therapy resistance, and tissue remodeling through lactylation and metabolite signaling. Tumor studies show that lowering lactate can restore CD8⁺T-cell activity, maintain M1 macrophage polarization, and destabilize PD-L1 42735733Sep42615169Aug42491336Jul. Huachansu tablets reduced tumor-derived lactate through the ChREBP/PKLR-lactate axis, while NAT1 restrained ENO1 activity and lactate production 42735733Sep42491336Jul. Lactate produced opposing tissue effects in other models: it stabilized HIF-1α in chondro-modulatory tenocytes but promoted mesenchymal stem cell osteogenesis through histone lactylation 42660868Aug42498150Jul. Cryptotanshinone reduced ENO1 activity, H3K18 lactylation, MGAT4A expression, GLUT1 membrane localization, and glucose uptake in gastric cancer, whereas lactate-mediated BMAL1 lactylation drove VEGFA expression and bevacizumab resistance in glioblastoma 42235355Jun41995718Apr. Axis-directed interventions now include lactate oxidase hydrogels, temsirolimus, glycolytic modulation, lactate transporter inhibition, and combinations with immune checkpoint inhibitors 42615169Aug42660868Aug42735733Sep41995718Apr.

Lactate Risk in Critical Care: Serum lactate rises alongside renal dysfunction in diabetic kidney disease and correlates with cystatin C and creatinine, although the authors interpret it as a marker of metabolic and hemodynamic stress rather than a disease-specific mediator 42743268Sep. Prehospital lactate was higher in severely injured trauma patients, but its discrimination for severe injury, major anatomic injury, and prolonged ICU admission remained limited 42584683Aug. In ICU-admitted acute pancreatitis, a high lactate-to-albumin ratio strongly predicted 28-day mortality, and an Extratrees model combining LAR, RAR, BAR, age, creatinine, and other variables retained performance during external validation 42259120Jun. Critical-care registry studies also show that lactate missingness reflects patient severity, so multiple imputation changes IABP-SHOCK II risk classification and reduces selection and measurement bias 42486195Jul. The field is moving toward validated, multimodal risk models that combine lactate with albumin-derived indices, renal markers, established trauma criteria, and principled missing-data methods.

Wearable Lactate Sensing: Flexible sweat platforms increasingly combine lactate sensing with multiplexed metabolite, electrolyte, and physiological measurements. A conformal L012-Au nanocomposite/laser-induced graphene electrochemiluminescence array detected glucose and lactate simultaneously, with limits of detection below 1.0 μM and stable output after repeated bending 42503751Jul. An impedance-engineered ionic hydrogel provided a lactate channel with a 0.1–6 mM linear range, an approximately 12 μM detection limit, and rapid response alongside glucose sensing and ECG acquisition 42143895May. A CuS/PDA@MXene electrochemical layer measured lactate across 0.5–12 mM, while hydrogel-embedded microfluidics and colorimetric chips tracked sweat flow, pH, temperature, and UV intensity 42061345Apr. Current development emphasizes sensitivity, broad linear range, mechanical stability, skin-compatible integration, multimodal readouts, and machine-learning analysis for real-time sweat monitoring.
