Regulatory T cells diminish transmission of HIV from Dendritic cells to conventional CD4+ T cells

Frontiers in Immunology, 2014
Formation of immunological synapses between dendritic cells (DC) and conventional CD4+ T cells (Tcon) is critical for productive immune responses. However, when DCs are HIV-infected such synapses are critical to establish HIV infection.

Engineering Assembloids to Mimic Graft‐Host Skeletal Muscle Interaction

Advanced Healthcare Materials, EarlyView.
This study develops a graft‐host skeletal muscle assembloid model combining neuromuscular organoids with tissue‐engineered constructs. Pre‐seeding decellularized muscles with myogenic cells enhances cell migration and axon invasion from the organoid. The model exhibits regenerative capacity following acute damage, advancing the understanding of human ...

MHC Class I Stability is Modulated by Cell Surface Sialylation in Human Dendritic Cells

Pharmaceutics, 2020
Maturation of human Dendritic Cells (DCs) is characterized by increased expression of antigen presentation molecules, and overall decreased levels of sialic acid at cell surface. Here, we aimed to identify sialylated proteins at DC surface and comprehend

PRMT3‐Mediated H4R3me2a Promotes Primary Age‐Related Tauopathy by Driving Tau Hyperphosphorylation in Neuron

Advanced Science, EarlyView.
This study identifies PRMT3‐mediated H4R3me2a as a critical driver of tau hyperphosphorylation in primary age‐related tauopathy. Mechanistic insights reveal that the PRMT3/H4R3me2a/miR‐448 axis suppresses IGF1R expression via epigenetic regulation, further dysregulating the PI3K/AKT/GSK3β pathway.
