The mammalian Krüppel-like factors (KLFs) are a family of zinc-finger containing transcription factors with diverse patterns of expression and a wide array of cellular functions. While their roles in mammalian physiology are well known, there is a growing appreciation for their roles in modulating the fundamental progression of aging. Here we review the current knowledge of Krüppel-like factors with a focus on their roles in processes regulating aging and age-associated diseases.

Background: In Alzheimer's Disease trials, the Mini-Mental State Examination (MMSE) and Clinical Dementia Rating (CDR) are commonly utilized as inclusionary criteria at screening. These measures, however, do not always reaffirm inclusionary status at baseline. Score changes between screening and baseline visits may imply potential score inflation at screening leading to inappropriate participant enrollment.

Background: Genetic studies indicate a causal role for microglia, the innate immune cells of the central nervous system (CNS), in Alzheimer's disease (AD). Despite the progress made in identifying genetic risk factors, such as CD33, and underlying molecular changes, there are currently limited treatment options for AD. Based on the immune-inhibitory function of CD33, we hypothesize that inhibition of CD33 activation may reverse microglial suppression and restore their ability to resolve inflammatory processes and mitigate pathogenic amyloid plaques, which may be neuroprotective.

Background: Alzheimer's disease (AD) trials report a high screening failure rate (potentially eligible trial candidates who do not meet inclusion/exclusion criteria during screening) due to multiple factors including stringent eligibility criteria. Here, we report the main reasons for screening failure in the 12-week screening phase of the ongoing evoke (NCT04777396) and evoke+ (NCT04777409) trials of semaglutide in early AD.
Method: Key inclusion criteria were age 55-85 years; mild cognitive impairment due to AD (Clinical Dementia Rating [CDR] global score of 0.

Background: Astrocytes, a major glial cell in the central nervous system (CNS), can become reactive in response to inflammation or injury, and release toxic factors that kill specific subtypes of neurons. Over the past several decades, many groups report that reactive astrocytes are present in the brains of patients with Alzheimer's disease, as well as several other neurodegenerative diseases. In addition, reactive astrocyte sub-types most associated with these diseases are now reported to be present during CNS cancers of several types.

Background: The Apolipoprotein E4 isoform (ApoE4), encoded by the APOE gene, stands out as the most influential genetic factor in late-onset Alzheimer's disease (LOAD). The ApoE4 isoform contributes to metabolic and neuropathological abnormalities during brain aging, with a strong correlation observed in APOE4-positive Alzheimer's disease cases between phosphorylated tau burden and amyloid deposition. Despite compelling evidence of APOE-mediated neuroinflammation influencing the progression of tau-mediated neurodegeneration, the molecular mechanisms underlying these phenomena remain largely unknown.
