PLD1 and PLD2 differentially regulate the balance of macrophage polarization in inflammation and tissue injury.

Phospholipase D (PLD) isoforms PLD1 and PLD2 serve as the primary nodes where diverse signaling pathways converge. However, their isoform-specific functions remain unclear. We showed that PLD1 and PLD2 selectively couple to toll-like receptor 4 (TLR4) and interleukin 4 receptor (IL-4R) and differentially regulate macrophage polarization of M1 and M2 via the LPS-MyD88 axis and the IL-4-JAK3 signaling, respectively.

The effects of pinoresinol on cholinergic dysfunction-induced memory impairments and synaptic plasticity in mice.

Dementia is a category of brain diseases that cause a decrease in cognitive functions. Alzheimer's disease (AD) is the most frequently mentioned neurodegenerative disease showing dementia. Although many useful drugs for dementia were developed, we still need better and safer drugs.
