Light chain amyloidosis is a deadly disease in which a monoclonal plasma cell dyscrasia produces misfolded immunoglobulin light chains (AL) that aggregate and form rigid amyloid fibrils. The amyloid deposits infiltrate one or more organs, leading to injury and severe dysfunction. The degree of cardiac involvement is a major driver of morbidity and mortality. Early diagnosis and treatment are crucial to prevent irreversible end-organ damage and improve overall survival. Treatment of AL cardiac amyloidosis involves eliminating the underlying plasma cell dyscrasia with chemotherapy and pursuing supportive heart failure management.

Background: Progranulin (GRN) plays a critical role in familial frontotemporal dementia (fFTD), where GRN haploinsufficiency leads to reduction in PGRN levels in the brain, resulting in degeneration of neurons in the frontal lobe of brain responsible for personality, language, and behavior. FTD is the most common dementia in people under 60. Sortilin (Sort1), expressed by neurons, endocytoses, and delivers PGRN rapidly to lysosomes for degradation.

Background: Global epidemiological studies involving over nine million participants have shown a 35% lower incidence of Alzheimer's Disease (AD) in older cancer survivors compared to those without a history of cancer. This inverse relationship, consistent across recent studies with methodological controls, suggests that cancer itself, rather than cancer treatments, may offer protective factors against AD. This insight opens avenues for novel therapeutic strategies targeting early AD by harnessing cancer-associated protective factors.

Background: Cognitive decline associated with Alzheimer's disease (AD) correlates with hyperphosphorylated tau (pTau) propagating between neurons along networks connected by synapses. It has been hypothesized this transcellular transmission occurs partially by extracellular vesicles (EVs). Both genetic and pharmacological inhibition of nSMase2 has been found to inhibit EV biogenesis and pTau propagation.

Background: The risk of cognitive decline in cancer survivors may be increased by platinum-based chemotherapy. Evidence indicates that physical exercise has a potential to reduce chemotherapy-related toxicity. The aim of this study was to assess effects of a 6-month aerobic-strength training on cognitive functions, metabolic flexibility, anthropometric parameters and physical fitness in testicular germ cell tumor (TGCT) survivors, treated with platinum-based chemotherapy.

Von Willebrand factor (VWF) plays a critical role in hemostasis, and emerging evidence suggests its involvement in inflammation. Our study aimed to investigate the interaction between circulating plasma VWF and neutrophils (polymorphonuclear cells, PMNs), elucidate the fate of VWF after binding, and explore its impact on neutrophil behavior. Neutrophils were isolated from the whole blood of healthy volunteers, and their interaction with plasma VWF was examined ex vivo.
