Background: Proenkephalin A 119-159 (penKid) is a novel blood biomarker for real-time assessment of kidney function and was found to be independently associated with worsening kidney function and mortality. A novel penKid-based estimated glomerular filtration rate equation (eGFR), outperforms current creatinine-based eGFR equations in predicting iohexol or iothalamate plasma clearance-based measured GFR. In this study, we aimed to evaluate the predictive value of penKid and eGFR for all-cause mortality in stable patients at high cardiovascular risk.

Patients with Inflammatory Bowel Disease (IBD) undergoing immunosuppressive therapies face heightened susceptibility to severe COVID-19. An in-depth understanding of systemic inflammation and cellular immune responses after SARS-CoV-2 vaccination and breakthrough infections (BTI) is required for optimizing vaccine strategies in this population. While the prevalence of high serological responders post- third COVID-19 vaccine dose was lower, and the antibody waning was higher in IBD patients than in healthy donors (HD), IBD patients showed an increase in anti-RBD Wild Type IgG levels and cross-reactive Spike -specific memory B cells following BTI.

Article Synopsis
  • Patients with rare lipid disorders have specific sterols that accumulate in their blood, making accurate measurement crucial for diagnosis and treatment monitoring.
  • Existing methods to test sterols can be complicated and time-consuming, limiting access to tests in many areas.
  • A new, simple method using isotope-dilution LC-MS/MS was developed to quickly extract and measure sterols in blood, validated through analysis of serum samples from both healthy controls and patients, showing significant differences in sterol levels linked to various disorders.

Neurodegenerative diseases are often accompanied by neuroinflammation and impairment of the blood-brain barrier (BBB) mediated by activated glial cells through their release of proinflammatory molecules. To study the effects of glial cells on mouse brain endothelial cells (mBECs), we developed an in vitro BBB model with inflammation by preactivating mixed glial cells (MGCs) with lipopolysaccharide (LPS) before co-culturing with mBECs to study the influence of molecules released by activated MGCs. The response of the mBECs to activated MGCs was compared to direct stimulation with LPS.

Denosumab is a monoclonal anti-RANKL antibody that inhibits bone resorption, increases bone mass, and reduces fracture risk. Denosumab discontinuation causes an extensive wave of rebound resorption, but the cellular mechanisms remain poorly characterized. We utilized in situ hybridization (ISH) as a direct approach to identify the cells that activate osteoclastogenesis through the RANKL/OPG pathway.

A key step in developing engineered B cells for therapeutic purposes is evaluation in immunocompetent, large-animal models. Therefore, we developed methods to purify, expand, and differentiate non-human primate (NHP; rhesus macaque) B cells. After 7 days in culture, B cells expanded 10-fold, differentiated into a plasma cell phenotype (CD38, CD138), and secreted immunoglobulin G.

Article Synopsis
  • The study aimed to compare immune responses to a COVID-19 booster vaccination between older adults and younger individuals, focusing on humoral and cellular immunity.
  • Researchers found that older adults (average age 86) initially had lower immune responses after earlier vaccinations compared to younger adults (average age 39), but both groups improved their antibody levels after the booster.
  • While young adults showed increased cellular immune responses after the booster, older adults did not, and their plasma showed higher levels of certain T cell activation and exhaustion markers, indicating potential immune dysfunction in the elderly.

The COVID-19 pandemic posed a challenge for people living with HIV (PLWH), particularly immune non-responders (INR) with compromised CD4 T-cell reconstitution following antiretroviral therapy (CD4 count <350 cells per mm). Their diminished vaccine responses raised concerns about their vulnerability to SARS-CoV-2 breakthrough infections (BTI). Our in-depth study here revealed chronic inflammation in PLWH and a limited anti-Spike IgG response after vaccination in INR.

Article Synopsis
  • The study aimed to examine how acid etch and silane contamination affect the bond strength of composite materials when repairing teeth and their adhesion to dentin.
  • Forty composite blocks were tested under different contamination conditions and treated with various adhesives, revealing that Bis-Silane treatment improved bond strength, while acid contamination weakened it.
  • Results showed that silane contamination on dentin negatively impacted the bond strength, and additional cleaning attempts did not restore strength; the majority of failures were adhesive in nature.

Background: In patients with coronary artery disease, coronary plaques with high-risk features and low-attenuation plaque burden are independent measures associated with major adverse cardiovascular events (MACEs). Patients with chronic kidney failure may have different coronary artery disease characteristics. The aim was to assess the association of coronary plaque characteristics and coronary artery disease extent with MACE and all-cause mortality in patients with chronic kidney failure.

The neurodegenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD) and Spinocerebellar ataxias (SCAs), present an enormous medical, social, financial and scientific problem. Despite intense research into the causes of these disorders, only marginal progress has been made in the clinic and no cures exist for any of them. Most of the scientific effort has been focused on identification of the major causes of these diseases and on developing ways to target them, such as targeting amyloid accumulation for AD or targeting expression of mutant Huntingtin for HD.

Background: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes. More precise timing of myocardial injuries necessitates separation of these 2 components.

Pro-inflammatory autoantigen-specific CD4 T helper (auto-Th) cells are central orchestrators of autoimmune diseases (AIDs). We aimed to characterize these cells in human AIDs with defined autoantigens by combining human leukocyte antigen (HLA)-tetramer-based and activation-based multidimensional ex vivo analyses. In aquaporin4-antibody-positive neuromyelitis optica spectrum disorder (AQP4-NMOSD) patients, auto-Th cells expressed CD154, but proliferative capacity and pro-inflammatory cytokines were strongly reduced.

Antibody inhibitors pose an ongoing challenge to the treatment of subjects with inherited protein deficiency disorders, limiting the efficacy of both protein replacement therapy and corrective gene therapy. Beyond their central role as producers of serum antibody, B cells also exhibit many unique properties that could be exploited in cell therapy applications, notably including antigen-specific recognition and the linked capacity for antigen presentation. Here we employed CRISPR-Cas9 to demonstrate that ex vivo antigen-primed Blimp1-knockout "decoy" B cells, incapable of differentiation into plasma cells, participated in and downregulated host antigen-specific humoral responses after adoptive transfer.
