Simian betaretroviruses include the well-known exogenous simian retroviruses (SRV-1 through SRV-8), and some closely related simian endogenous retroviruses (SERV). Here, we characterized two new viral genomes, which appear to represent novel SERVs but have characteristics of both SRV and SERV highlighting the need to develop new assays providing molecular and serologic differentiation of SERV and SRV to avoid false positives.

Antibody-secreting cells (ASCs) are generated following B cell activation and constitutively secrete antibodies. As such, ASCs are key mediators of humoral immunity whether it be in the context of pathogen exposure, vaccination or even homeostatic clearance of cellular debris. Therefore, understanding basic tenants of ASC biology such as their differentiation kinetics following B cell stimulation is of importance.

Chemical synaptic transmission involves neurotransmitter release from presynaptic active zones (AZs). The AZ protein Rab-3-interacting molecule (RIM) is important for normal Ca-triggered release. However, its precise localization within AZs of the glutamatergic neuromuscular junctions of remains elusive.

The genomes of mammals contain fingerprints of past infections by ancient retroviruses that invaded the germline of their ancestors. Most of these endogenous retroviruses (ERVs) contain only remnants of the original retrovirus; however, on rare occasions, ERV genes can be co-opted for a beneficial host function. While most studies of co-opted ERVs have focused on envelope genes, including the syncytins that function in placentation, there are examples of co-opted genes including one we recently discovered in simian primates.

Formosan macaque (Macaca cyclopis) is the only non-human primate in Taiwan Island. We performed de novo hybrid assembly for M. cyclopis using Illumina paired-end short reads, mate-pair reads and Nanopore long reads and obtained 5065 contigs with a N50 of 2.

Article Synopsis
  • The study explores how envelope (env) genes from retroviruses have impacted placental development in therian mammals, focusing on their presence in egg-laying monotremes like the platypus and echidna.
  • Researchers identified only two env-derived open reading frames (env-ORFs) in the platypus genome but found 121 in the echidna, categorizing them into seven phylogenetic groups, with the env-Tac1 group showing notable similarities to certain retroviruses.
  • The Env-Tac1 protein from echidnas was shown to facilitate cell fusion in human cells using specific receptors, suggesting that retroviral env genes play a role in cell fusion beyond just placental
