Association between cognitive decline and depression in middle-aged and older adults: Findings from six large cohorts in different countries.

Background: The relationship between depression and cognition in middle-aged adults is a topic of interest. Whether poor cognitive function exacerbates depression remains controversial. We clarified the association between cognitive decline and depression based on six nationwide cohorts.

CD4 T-cell epitope-based heterologous prime-boost vaccination potentiates anti-tumor immunity and PD-1/PD-L1 immunotherapy.

Background: Antitumor therapeutic vaccines are generally based on antigenic epitopes presented by major histocompatibility complex (MHC-I) molecules to induce tumor-specific CD8 T cells. Paradoxically, continuous T cell receptor (TCR) stimulation from tumor-derived CD8 T-cell epitopes can drive the functional exhaustion of tumor-specific CD8 T cells. Tumor-specific type-I helper CD4 T (T1) cells play an important role in the population maintenance and cytotoxic function of exhausted tumor-specific CD8 T cells in the tumor microenvironment.

Lithium carbonate alleviates colon inflammation through modulating gut microbiota and Treg cells in a GPR43-dependent manner.

Background: Recent evidence suggests that neuropsychiatric stabilizers have a place in resolving gastrointestinal disorders. Lithium carbonate (LC) is one of the most commonly used drugs for bipolar disorder clinically. Here, we estimate the therapeutic function of LC against colitis and investigate the mechanism of intestinal flora and metabolism modulation.

Parabacteroides produces acetate to alleviate heparanase-exacerbated acute pancreatitis through reducing neutrophil infiltration.

Background: The endoglycosidase heparanase which degrades heparan sulfate proteoglycans, exerts a pro-inflammatory mediator in various inflammatory disorders. However, the function and underlying mechanism of heparanase in acute pancreatitis remain poorly understood. Here, we investigated the interplay between heparanase and the gut microbiota in the development of acute pancreatitis.
