Summary: The study found that early accumulation of A beta protein in Alzheimer's disease has an independent effect on cognitive decline in normal controls, but has a tau and neurodegeneration-dependent effect on subsequent cognitive decline in patients with mild cognitive impairment.

Summary: The amyloid cascade hypothesis has played a significant role in Alzheimer's disease research and clinical trial designs. This study investigated the relationship between amyloid-beta and tau at the individual and twin-pair levels, aiming to rule out genetic and shared environmental effects as confounders. The findings suggest that the associations between amyloid-beta, tau, neurodegeneration, and cognition are unbiased by genetic factors, and the effects of amyloid-beta on neurodegeneration and cognitive decline are mediated by tau.

Summary: MOS-Sia can reduce the beta-structure formation of A beta 42, with MOS-Sia3 showing a more pronounced effect, and also exhibit a good complexing effect with Ca2+. Furthermore, MOS-Sia3 can inhibit BV-2 cells activated by A beta 42 and reduce the expression of proinflammatory factors.

Summary: Hearing loss in older adults is associated with increased dementia risk, and the underlying mechanisms connecting the two remain unclear. This study found an association between hearing loss and biomarkers for dementia risk, and the association varied between different age groups. In older adults, hearing loss was associated with a decline in memory, global cognition, and language.

Summary: The diazepam-binding inhibitor (DBI)-derived peptide octadecaneuropeptide (ODN) has been found to have potent neuroprotective effects against amyloid-beta peptide (Aβ)-induced neurotoxicity and memory decline in Alzheimer's disease (AD). Its antioxidant properties contribute to the reduction of oxidative stress, mitochondrial dysfunction, and apoptosis. These findings suggest that ODN may be a potential therapeutic agent for AD.

Summary: In this study, the synthesis of nanosized, functional gallic acid-based dendrimers is described, which interact with Aβ species and remodel them into noncytotoxic aggregates. The multivalent presentation of gallic acid on the dendrimer surface enhances their ability to interact with Aβ, inhibiting fibrillization and disrupting preformed fibrils.

Summary: We examined the prevalence of AD pathological hallmarks in HIV-infected individuals and found that AD pathology was less prevalent and less severe in HIV-positive individuals compared to HIV-negative individuals. AD pathology was most consistently related to memory-related domains in HIV-positive individuals. Further studies are needed to investigate the effect of HIV status on AD pathology.

Summary: Alzheimer's disease is the most common form of dementia and is responsible for 60-70% of cases. The number of people with dementia is expected to triple by 2050 due to an aging population. Currently, there are only symptomatic treatments available, making it crucial to develop novel therapeutic strategies to prevent or delay the onset of Alzheimer's disease. This mini-review focuses on the understanding of Alzheimer's disease pathobiology and discusses current immunomodulating therapies targeting amyloid-beta protein.

Summary: Traumatic brain injury (TBI) impairs cellular energy demand, compromising neuronal function and plasticity. This study demonstrates that the mitochondrial activator humanin (HN) can counteract the reduction in mitochondrial bioenergetics caused by TBI, restore memory function and synaptic protein levels, and suppress inflammation and astrocyte proliferation. HN plays an integral role in normalizing fundamental aspects of TBI pathology.

Summary: Progress has been made in the treatment of Alzheimer's disease through the development of anti-A beta therapeutics, which have shown modest efficacy in slowing the progression of the disease. However, the puzzling issue remains as to why completely removing A beta does not fully stop the disease.

Summary: Colorectal cancer often requires adjuvant therapies to reduce tumor burden, and the efficacy of these therapies is significantly influenced by reactive oxygen species (ROS). ROS-mediated colorectal cancer adjuvant therapies involve multiple mechanisms, and preliminary clinical trials have shown the potential of ROS-manipulating therapy in enhancing treatment outcomes.

Summary: Pancreatic adenocarcinoma (PAAD) is a common digestive malignant tumor with limited treatment options. This study demonstrates that TGM2 may serve as a marker for treatment and prognosis in pancreatic cancer patients. Co-treatment of low dose cisplatin (DDP) and the TGM2 inhibitor GK921 effectively inhibits PAAD cell viability and proliferation in vitro and in vivo, by inhibiting epithelial-to-mesenchymal transition (EMT) induced by TGM2 and enhancing cell cycle arrest and apoptosis caused by DDP. These findings suggest that the combination of GK921 and DDP holds promise as a treatment for PAAD patients.

Summary: Depression is a common neuropsychiatric comorbidity in Alzheimer's disease (AD) and other Tauopathies. Selective serotonin reuptake inhibitor (SSRI) treatment, such as Citalopram, not only has anti-depressive and anxiolytic effects, but also helps improve neurogenesis, reduce amyloid burden & Tau pathologies, and neuroinflammation in AD. In this study, Citalopram was found to reduce pathologically pTau level, increase synaptic gene expression and cytoskeletal structure, as well as improve cell survival, mitochondrial respiration, and mitochondrial morphology in cells expressing mutant APP and Tau. These findings suggest that Citalopram could be a promising therapeutic drug for treating depression and AD.

Summary: Bone is a self-healing organ that undergoes continuous regeneration through the cooperation of osteoclasts and osteoblasts. This study used ATAC-seq and RNA-Seq techniques to investigate the chromatin accessibility and transcriptomic landscape of osteoblast differentiation and mineralization. The results showed that global chromatin accessibility was extensively improved during osteoblastogenesis. Additionally, several transcription factors including MEF2A, PRRX1, Shox2, and HOXB13 were found to modulate the promoter accessibility of target genes during osteoblast differentiation.

Summary: Congenital sucrase-isomaltase deficiency (CSID) is an autosomal recessive disorder caused by variants in the SI gene. A frameshift mutation called c.273_274delAG (p.Gly92Leufs*8) has been identified in CSID patients in Greenlandic population, which leads to loss of digestive function of SI. Surprisingly, the truncated mutant can still be located on the cell surface and interacts with wild type SI, negatively affecting its enzymatic function. Furthermore, heterozygote carriers of this mutation may also exhibit CSID symptoms.
