Article Abstract

A captive 17-year-old male cynomolgus monkey (Macaca fascicularis) developed diffuse large B-cell lymphoma (DLBCL). This was the first report of DLBCL presenting with a mandible mass and violation of the paranasal sinus in a cynomolgus monkey. The neoplasm showed marked microscopical malignant aspects. Immunohistochemical staining showed strong positive expression of CD20. These features may contribute to the diagnosis and therapeutics of DLBCL in NHPs.

Zona pellucida glycoprotein-1 (ZP1) is essential for maintaining oocyte structural integrity and facilitating fertilization. Mutations in are strongly associated with primary infertility disorders such as fertilization failure and empty follicle syndrome; however, the absence of accurate experimental models has hindered mechanistic understanding and obscured the etiological basis of -related infertility. In this study, CRISPR/Cas9-mediated genome editing was employed to generate two -edited cynomolgus macaques ( ), designated #ZP1-1 (male) and #ZP1-2 (female).

Background: The long-term clinical efficacy of intraportal islet transplantation is hampered by islet loss due to inflammation, oxidative stress, and insufficient vascularization. This study explores the venous sac as an alternative implantation site for islet transplantation in large animal models.

Methods: An immunosuppressed, diabetic cynomolgus monkey received allogeneic islet implants in its mesenteric venous sac, with metabolic assessments over 112 days.

Background: A growing body of evidence from primate embryos as well as in vitro systems supports the notion that amnion and primordial germ cell (PGC) lineage progressing cells share a common precursor.

Results: To gain comprehensive transcriptomic insights into this critical but poorly understood precursor and its progeny, we examine the evolving transcriptome of a developing human pluripotent stem cell-derived model of amnion and PGC formation at the single cell level. This analysis reveals several continuous amniotic fate progressing states with state-specific markers.

Overcoming target interference in bridging anti-drug antibody (ADA) assay by optimizing sample treatment.

Bioanalysis

Background: Drug bridging immunoassays are widely employed as the standard approach for detecting anti-drug antibodies (ADAs) in the development of new biological entities. A major challenge in these assays is mitigating target interference, particularly when the soluble target exists in dimeric forms, which can result in false positive signals and compromise assay specificity.

Research Design And Methods: We developed sensitive and robust ADA assays capable of overcoming target interference to detect antibodies against BI X in both cynomolgus monkey (cyno) plasma and human serum matrices.

Angelman syndrome patient-derived neuron screen leads to clinical ASO rugonersen targeting UBE3A-ATS with long-lasting effect in monkeys.

Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by the loss of neuronal ubiquitin E3 ligase UBE3A, with no available treatment. Restoring UBE3A by downregulating the paternally cis-acting long noncoding antisense transcript (UBE3A-ATS) is a potentially disease modifying strategy. However, developing molecules targeting human UBE3A-ATS is challenging due to its selective expression in mature neurons and lack of sequence conservation across species.
