Cordycepin is the major bioactive component extracted from Cordyceps militaris. In recent years, cordycepin has received increasing attention owing to its multiple pharmacological activities. This ...study reviews recent researches on the anti‐inflammatory effects and the related activities of cordycepin. The results from our review indicate that cordycepin exerts protective effects against inflammatory injury for many diseases including acute lung injury (ALI), asthma, rheumatoid arthritis, Parkinson's disease (PD), hepatitis, atherosclerosis, and atopic dermatitis. Cordycepin regulates the NF‐κB, RIP2/Caspase‐1, Akt/GSK‐3β/p70S6K, TGF‐β/Smads, and Nrf2/HO‐1 signaling pathways among others. Several studies focusing on cordycepin derivatives were reviewed and found to down metabolic velocity of cordycepin and increase its bioavailability. Moreover, cordycepin enhanced immunity, inhibited the proliferation of viral RNA, and suppressed cytokine storms, thereby suggesting its potential to treat COVID‐19 and other viral infections. From the collected and reviewed information, this article provides the theoretical basis for the clinical applications of cordycepin and discusses the path for future studies focusing on expanding the medicinal use of cordycepin. Taken together, cordycepin and its analogs show great potential as the next new class of anti‐inflammatory agents.

Cerebral ischemia impairs physiological form of synaptic plasticity such as long-term potentiation (LTP). Clinical symptoms of cognitive dysfunction resulting from cerebral ischemia are associated ...with neuron loss and synaptic function impairment in hippocampus. It has been widely reported that cordycepin displays neuroprotective effect on ameliorating cognitive dysfunction induced by cerebral ischemia. Therefore, it is necessary to study whether cordycepin recovers cognitive function after brain ischemia through improving LTP induction. However, there has been very little discussion about the effects of cordycepin on LTP of cerebral ischemia so far. In the present study, we investigated the effects of cordycepin on LTP impairment and neuron loss induced by cerebral ischemia and excitotoxicity, using electrophysiological recording and Nissl staining techniques. The models were obtained by bilateral common carotid artery occlusion (BCCAO) and intrahippocampal NMDA microinjection. We also explored whether adenosine A1 receptors involve in the neuroprotection of cordycepin by using western blot. We found that cordycepin remarkably alleviated LTP impairment and protected pyramidal cell of hippocampal CA1 region against cerebral ischemia and excitotoxicity. Meanwhile, cordycepin prevented the reduction on adenosine A1 receptor level caused by ischemia but did not alter the adenosine A2A receptor level in hippocampal CA1 area. The improvement of LTP in the excitotoxic rats after cordycepin treatment could be blocked by DPCPX, a selective antagonist of adenosine A1 receptor. In summary, our findings provided new insights into the mechanisms of cordycepin neuroprotection in excitotoxic diseases, which is through regulating adenosine A1 receptor to improve LTP formation and neuronal survival.

•Enhancing therapeutic efficacy through the exploration of combination therapies involving immune checkpoint inhibitors is of paramount importance.•Recently, our research showcased the profound ...impact of a combination treatment involving cordycepin and the anti-CD47 antibody on tumor growth inhibition and extended lifespan in tumor-bearing mice.•In continuation, our present study successfully devised another combination therapeutic strategy incorporating cordycepin and CTLA-4 blockade, which demonstrated a remarkable synergistic effect against cancer.•To gain deeper insights into the underlying mechanisms, we conducted single-cell RNA sequencing and flow cytometry analyses to explore the remodeling of the tumor microenvironment, providing a comprehensive understanding of the intricate changes occurring at the cellular level.•These analyses illuminated the molecular interactions and immune modulation responsible for the observed therapeutic outcomes.
The strategy of using immune checkpoint inhibitors (ICIs) has revolutionized cancer treatment, leading to remarkable clinical outcomes. However, certain cancer types and patient demographics continue to face unique challenges. As a result, it is vital to investigate combination therapies that involve ICIs to boost therapeutic efficacy. Cordycepin, an adenosine derivative composed of adenine and pentose, holds immense promise for treating inflammation and cancer. Our recent research has demonstrated that the combined treatment of cordycepin and the anti-CD47 antibody significantly curtails tumor growth and extends the lifespan of tumor-bearing mice. In the current study, we showed that the combination of cordycepin and CTLA-4 blockade had a profound impact on suppressing tumor growth. We utilized the MC38 and CT26 tumor models to evaluate the therapeutic effect of cordycepin, CTLA-4 blockade, and their combined approach. Flow cytometry results unveiled that cordycepin, when combined with CTLA-4 blockade, considerably augmented the presence of tumor-infiltrating CD8+T cells and diminished the population of Foxp3+Tregs within the tumor microenvironment (TME). Additionally, we employed single-cell analysis to examine the TME’s reconfiguration upon the combined treatment of anti-CTLA-4 and cordycepin. We observed a significant impact on inhibiting tumor growth and substantially extended survival in tumor-bearing mice. Our data also demonstrated an increased proportion of effector CD8+T cells in the combined treatment group compared to all other groups, while exhausted CD8+T cells diminished in the combined group compared to the anti-CTLA-4 treatment alone. In conclusion, our findings supported the idea that combining cordycepin and CTLA-4 blockade could modify the effector and exhaustion status of CD8+T cells, thereby bolstering CD8+T-cell-mediated anti-tumor immunity in the TME. Collectively, our current study successfully established a combination therapeutic strategy utilizing cordycepin and CTLA-4 blockade. This strategy demonstrated a significant synergistic effect against cancer, highlighting its importance in cancer treatment.
Repeated-batch fermentation with fungal mycelia immobilized in plastic composite support (PCS) eliminates the lag phase during fermentation and improves metabolite productivity. The strategy is ...implemented herein, and a novel modified PCS is developed to enhance exopolysaccharide (EPS) production from the medicinal fungus Cordyceps militaris. A modified PCS (SYE + PCS) was made by compositing polypropylene (PP) with a nutrient mixture containing soybean hull, peptone, yeast extract, and minerals (SYE+). The use of SYE + PCS has consistent cell productivity throughout the multiple fermentation cycles, which resulted in a more higher cell productivity after second batch compared to unmodified PCS. The cell grown on SYE + PCS also generates a higher yield of EPS (3.36, 6.93, and 5.72 g/L in the first, second, and third fermentation cycles, respectively) up to three-fold higher than the cell immobilized on unmodified PCS. It is also worth noting that the EPS from mycelium grown on SYE + PCS contains up to 2.3-fold higher cordycepin than those on unmodified PCS. The presence of nutrients in SYE + PCS also affects the hydrophobicity and surface roughness of the PC, improving mycelial cell adhesion. This study also provides a preliminary antioxidant activity assessment of EPS from immobilized C. militaris grown with SYE + PCS.
