The role of HLA-G in human pregnancy.

Published: May 2008

Pregnancy in mammals featuring hemochorial placentation introduces a major conflict with the mother's immune system, which is dedicated to repelling invaders bearing foreign DNA and RNA. Numerous and highly sophisticated strategies for preventing mothers from rejecting their genetically different fetus(es) have now been identified. These involve production of novel soluble and membrane-bound molecules by uterine and placental cells. In humans, the placenta-derived molecules include glycoproteins derived from the HLA class Ib gene, HLA-G. Isoforms of HLA-G saturate the maternal-fetal interface and circulate in mothers throughout pregnancy. Uteroplacental immune privilege for the fetus and its associated tissues is believed to result when immune cells encounter HLA-G. Unequivocally demonstration of this concept requires experiments in animal models. Both the monkey and the baboon express molecules that are similar but not identical to HLA-G, and may comprise suitable animal models for establishing a central role for these proteins in pregnancy.

Prosocial Helping Behavior: Conceptual Issues and Neural Mechanisms.

Biol Psychiatry

March 2025

From Department of Neurobiology and Department of Biological Chemistry, David Geffen School of Medicine, University of California, Los Angeles, CA 90095, USA. Electronic address:

Prosocial helping behavior, characterized by voluntary actions taken to benefit others, plays a vital role in promoting cooperation and maintaining social bonds across human and animal social groups. In this review, we examine key conceptual issues surrounding prosocial behavior, focusing specifically on targeted helping and comforting actions. We outline the behavioral paradigms used to study these two types of prosocial behaviors and summarize recent insights into their underlying neural mechanisms.

Lipopeptides with different fatty acids (palmitic, palmitoleic, stearic, oleic, and linoleic acids) conjugated to CHSPKKKRKV were synthesised by a solid-phase peptide method using the Fmoc strategy (Fmoc-SPPS) on 2-CTC (2-chlorotritylchloride) resin. The lipopeptides were purified by RP-HPLC and characterised by ToF-ESI-MS and 1D-NMR. The capability of the lipopeptide to interact with the plasmid was evaluated by DNA agarose gel electrophoresis.

Common marmoset: An emerging non-human primate model for translational applications in brain disorders.

One of the fundamental challenges for modern neuroscience has been to translate discoveries from model organisms into effective therapeutics for human brain disorders. This challenge partly arises from the structural and functional differences between rodent and human brains [1]. To bridge this gap, non-human primates (NHPs) can be used as an intermediate step because of their genetic, physiological, and behavioral similarities to humans.

Neurodevelopmental impact of CNV models in ASD: Recent advances and future directions.

Curr Opin Neurobiol

Department of Physiology and Cell Biology, Kobe University School of Medicine, Chuo, Kobe 650-0017, Japan. Electronic address:

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication impairments and restricted, repetitive behaviors. ASD exhibits a strong genetic basis, with rare and common genetic variants contributing to its etiology. Copy number variations (CNVs), deletions or duplications of chromosomal segments, have emerged as key contributors to ASD risk.
