Antibody deposition is a defining pathological feature of multiple kidney diseases including lupus nephritis. In this issue of , Jiang and colleagues identify a novel genetic risk factor, , which predisposes individuals toward antibody deposition via a kidney-intrinsic mechanism.

Background: Antibody-mediated rejection (ABMR) has become one of the leading causes of chronic lung graft dysfunction. However, in lung transplantation, this entity is sometimes difficult and controversial to diagnose. It is mainly caused by the appearance of donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA), although there are situations with C4d deposits in biopsy in the absence of circulating DSA.

Background: Anti-amyloid-β (Aβ) immunotherapy trials have shown amyloid-related imaging abnormalities (ARIA) as the most common and serious adverse events linked to pathological changes in cerebral vasculature. Nevertheless, the mechanisms underlying how amyloid immunotherapy triggers vascular damage, increases vascular permeability, and results in microhemorrhages remains unclear. Notably, activation of perivascular macrophages and infiltration of peripheral immune cells have been implicated in regulating cerebrovascular damage.

Background: Sleep dysfunction is commonly seen in Alzheimer's disease (AD) and Progressive Supranuclear Palsy (PSP), potentially worsening these conditions. Investigating early neuropathological changes in human sleep-promoting neurons, which often precede cognitive decline, is crucial for understanding the basis for sleep dysfunction as possible treatments yet remain underexplored. We used postmortem brains of AD and PSP patients to quantify neuronal numbers and tau burden in the intermediate nucleus of the hypothalamus (IntN), VLPO analog, known for its role in sleep maintenance.

Background: Anti- Aβ monoclonal antibodies are the first FDA-approved treatments for AD that slow cognitive decline and lower Aβ plaques. Our goal is to identify the epitope specificities of antibodies in human blood that are associated with AD and NC and determine the predicted protein targets of these antibodies.
Method: 101 AD (MMSE < 27) and 98 NC (MMSE > 27) serum samples were obtained from the UCI tissue repository.

Background: Rodent models have been proved pivotal in Alzheimer's disease (AD) research. Nevertheless, the use of models that only recapitulate one aspect of AD neuropathology, and of early time points that might be excluding important features such as age-dependent inflammation and senescence, could hinder the development of effective AD therapeutics. Several tau immunotherapies are currently undergoing clinical trial.
