Article Abstract

Background: Behavioral, social, and physical characteristics are posited to distinguish the sexes, yet research on transcription-level sexual differences in the brain is limited. Here, we investigated sexually divergent brain transcriptomics in prepubertal cynomolgus macaques, a commonly used surrogate species to humans.

Methods: A transcriptomic profile using RNA sequencing was generated for the temporal lobe, ventral midbrain, and cerebellum of 3 female and 3 male cynomolgus macaques previously treated with an Adeno-associated virus vector mix. Statistical analyses to determine differentially expressed protein-coding genes in all three lobes were conducted using DeSeq2 with a false discovery rate corrected P value of .05.

Results: We identified target genes in the temporal lobe, ventral midbrain, and cerebellum with functions in translation, immunity, behavior, and neurological disorders that exhibited statistically significant sexually divergent expression.

Conclusions: We provide potential mechanistic insights to the epidemiological differences observed between the sexes with regards to mental health and infectious diseases, such as COVID19. Our results provide pre-pubertal information on sexual differences in non-human primate brain transcriptomics and may provide insight to health disparities between the biological sexes in humans.

Human B cell immunity to the influenza hemagglutinin (HA) stem, a universal vaccine target, is often stereotyped and immunogenetically restricted, posing hurdles to study outside of humans. Here, we show that cynomolgus macaques vaccinated with an HA stem immunogen elicit humanlike public B cell lineages targeting two major conserved sites of vulnerability, the central stem and anchor epitopes. Central stem antibodies were predominantly derived from V1-138, the macaque homolog of human V1-69, a V gene preferentially used in human central stem broadly neutralizing antibodies (bnAbs).

Purpose: Adaptive optics scanning light ophthalmoscopy (AOSLO) paired with intravitreal injection of a viral vector coding for the calcium indicator GCaMP has enabled visualization of neuronal activity in retinal ganglion cells (RGCs) at single cell resolution in the living eye. However, the inner limiting membrane (ILM) restricts viral transduction to the fovea in humans and non-human primates, hindering both therapeutic intervention and physiological study of the retina. To address this issue, we explored peeling the ILM before intravitreal injection to expand calcium imaging beyond the fovea in the living primate eye.

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).

LP-98 is a lipopeptide HIV fusion inhibitor showing strong treatment and pre-exposure prophylaxis efficacies in non-human primates. In this study, we further characterized its pharmacokinetics, long-lasting antiviral activity, and post-exposure prophylaxis (PEP) efficacy using 62 macaques. In cynomolgus macaques, LP-98 achieved high concentrations (C) with a half-life (T) of ∼31 h, and sustained an effective therapeutic concentration for two weeks post-injection.

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.
