Structural Constraints at the Trimer Apex Stabilize the HIV-1 Envelope in a Closed, Antibody-Protected Conformation

mBio, 2018
The human immunodeficiency virus type 1 (HIV-1) envelope (Env) trimer evades antibody recognition by adopting a closed prefusion conformation. Here, we show that two conserved tyrosines (Y173, Y177) within the second variable (V2) loop of the gp120 Env ...

Early synovial regulatory T cell engagement in posttraumatic osteoarthritis

Arthritis &Rheumatology, Accepted Article.
Objective Posttraumatic osteoarthritis (PTOA) develops despite restoration of joint biomechanics, suggesting that early post‐injury biological processes within the synovium shape disease trajectories. We investigated whether synovial regulatory T (Treg) cells are engaged during the early phase following joint injury and whether experimental enrichment ...

Intact, recombinant, and spliced forms of endogenous mouse mammary tumor viruses in inbred and wild mice

Journal of Virology
Endogenous retroviruses (ERVs) are chromosomally integrated viral copies that represent relics of past infections. Analysis of the sequenced genomes of 17 mouse strains, Mus musculus subspecies, and Mus spretus identified 29 ERVs of mouse mammary tumor ...

Helminth-induced immunoregulation: an update

, 2016
Helminth infections, which have been reduced or eradicated from most developed countries, produce important changes in the immune system. Especially, when chronic and intense, they cause immunosuppression.

Glycosylated dendrimer nanoamplifiers hijack DNA damage‐immune crosstalk for enhanced dual‐track therapy of orthotopic glioblastoma

BMEMat, EarlyView.
A glycosylated dendrimer nanoamplifier hijacks DNA damage‐immune crosstalk for enhanced radio‐immunotherapy of glioblastoma. The responsive release of demethylcantharidin simultaneously blocks repair‐mediated resistance by inhibiting DNA repair and overcomes adaptive immune resistance.

Tannic acid–metal biomaterials for skin repair: Principles, immune microenvironment modulation, and translational perspectives

BMEMat, EarlyView.
Tannic acid–metal materials are emerging as versatile wound biomaterials, but their value depends on more than multifunctionality. This review maps how tannic acid alone, free metal ions, and coordinated TA–metal systems differ in design logic, immune‐microenvironment effects, and translational potential, offering a practical framework for choosing ...
