The construction of a cynomolgus macaque (Macaca fascicularis, Mafa) BAC library for genomic comparison between rhesus and cynomolgus macaques is necessary to promote the cynomolgus macaque as one of the important experimental animals for future medical and biological research. In this paper, we constructed a cynomolgus macaque BAC library and a map of the MHC (Mafa) genomic region for comparison of the genomic organization and nucleotide similarities between the human, the chimpanzee, and the rhesus macaque. The BAC library consists of 221,184 clones with an average insert size of 83 kb, providing a sixfold coverage of the haploid genome. A total of 114 BAC clones and 54 PCR primer sets were used to construct a 4.3-Mb contig of the MHC region. Diversity analysis of genomic sequence from selected subregions of the MHC revealed that the cynomolgus sequence varied compared to rhesus macaque, human, and chimpanzee sequences by 0.48, 4.15, and 4.10%, respectively. From these findings, we conclude that the BAC library and Mafa genomic map are useful tools for genome analysis and will have important applications for comparative genomics and identifying regions of consequence in medical research.

Spondyloarthritis is a prevalent and persistent condition that significantly impacts the quality of life. Its intricate pathological mechanisms have led to a scarcity of animal models capable of replicating the disease progression in humans, making it a prominent area of research interest in the field. To delve into the pathological and physiological traits of spontaneous non-human primate spondyloarthritis, this study meticulously examined the disease features of this natural disease model through an array of techniques including X-ray imaging, MRI imaging, blood biochemistry, markers of bone metabolism, transcriptomics, proteomics, and metabolomics.

Background: Nemolizumab, a humanized monoclonal antibody against interleukin-31 receptor A (IL-31RA), is used to treat atopic dermatitis and prurigo nodularis. These inflammatory skin diseases affect a wide range of age groups, including pregnant women and children; however, little is known about their biological effects on pre- and postnatal development. Therefore, we report and discuss the results of an enhanced pre- and postnatal development study in cynomolgus monkeys treated with nemolizumab, which also incorporates an assessment of juvenile toxicities.

Social housing changes are likely stressful and can be associated with diarrhea, the most common health problem noted in captive macaque populations. Diarrhea may reflect a negative shift in the gut flora ("gut dysbiosis"). This study reported on changes in the gut microbiome composition of juvenile primates () that experienced a change in social housing and exhibited diarrhea.

Small interfering RNA (siRNA) has shown promising results for the treatment of Charcot-Marie-Tooth disease 1A (CMT1A) caused by overexpression of peripheral myelin protein (PMP22), leading to myelin dysfunction and axonal damage. Recently, we developed siRNA PMP22-squalene (SQ) nanoparticles (NPs) for intravenous use. Three consecutive injections of siRNA PMP22-SQ NPs at a cumulative dose of 1.

The opioid crisis, driven by synthetic opioids like fentanyl, demands innovative solutions. The opioid antidote naloxone has a short action ( ~ 1 hour), requiring repeated doses. To address this, we present a new and simple naloxone prodrug delivery system repurposing a hydrophilic derivative of acoramidis, a potent transthyretin ligand.
