Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

open access: yesNature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.

Transcriptional activators and activation mechanisms [PDF]

open access: yesProtein & Cell, 2007
Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation. This article examines a few selected issues in understanding activator functions and activation mechanisms.

Active learning activities

open access: yesSeptentrio Conference Series, 2020
First year architecture students are introduced to the library by taking part in an “Escape Room” activity in the KTH library. The aim of this initiative is to introduce the students to the library space and the library's resources in an interactive and playful way and to enable them to learn and reflect upon their learning within the frame of an ...

Not All Immune Checkpoints Are Created Equal

open access: yesFrontiers in Immunology, 2018
Antibodies that block T cell inhibition via the immune checkpoints CTLA-4 and PD-1 have revolutionized cancer therapy during the last 15 years. T cells express additional inhibitory surface receptors that are considered to have potential as targets in ...

FcγR requirements and costimulatory capacity of Urelumab, Utomilumab, and Varlilumab

open access: yesFrontiers in Immunology, 2023
IntroductionTargeting costimulatory receptors of the tumor necrosis factor receptor (TNFR) superfamily with agonistic antibodies is a promising approach in cancer immuno therapy.

Active colloidal molecules in activity gradients [PDF]

open access: yesPhysical Review E, 2022
We consider a rigid assembly of two active Brownian particles, forming an active colloidal dimer, in a gradient of activity. We show analytically that depending on the relative orientation of the two particles the active dimer accumulates in regions of either high or low activity, corresponding to, respectively, chemotaxis and antichemotaxis.

Loss of RASGRP1 in humans impairs T‐cell expansion leading to Epstein‐Barr virus susceptibility

open access: yesEMBO Molecular Medicine, 2018
Inherited CTPS1, CD27, and CD70 deficiencies in humans have revealed key factors of T‐lymphocyte expansion, a critical prerequisite for an efficient immunity to Epstein–Barr virus (EBV) infection.

Cryomicroscopy reveals the structural basis for a flexible hinge motion in the immunoglobulin M pentamer

open access: yesNature Communications, 2022
Immunoglobulin M (IgM) is the Ig isotype that serves as the first line of host defence during infection. Here, the authors image the full-length IgM pentamer by cryo-EM, revealing the structure and hinge motion of the antigen binding domains.

Retrograde and Anterograde Transport of Lat-Vesicles during the Immunological Synapse Formation: Defining the Finely-Tuned Mechanism

open access: yesCells, 2021
LAT is an important player of the signaling cascade induced by TCR activation. This adapter molecule is present at the plasma membrane of T lymphocytes and more abundantly in intracellular compartments.

Skap2 is required for β2 integrin-mediated neutrophil recruitment and functions. [PDF]

open access: yes, 2017
Integrin activation is required for neutrophil functions. Impaired integrin activation on neutrophils is the hallmark of leukocyte adhesion deficiency (LAD) syndrome in humans, characterized by impaired leukocyte recruitment and recurrent infections. The
