Effects of Repeated Lipopolysaccharide Stimulation on the Development of Antigen-presenting Cells and T Cells Pool in Hen Vagina

open access: yesThe Journal of Poultry Science, 2013
The aim of this study was to determine how the mucosal immunity mediated by T cells is developed in the vagina. Antigen-presenting cells and T cells play important roles in the early process of host defense.

Rare event simulation for probabilistic models of T-cell activation

open access: yes, 2010
Lipsmeier F. Rare event simulation for probabilistic models of T-cell activation. Bielefeld (Germany): Bielefeld University; 2010.One of the central questions in immunobiology is: How does the immune system reliably distinguish between antigens of our ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Role of Vitamin D in the Immune System

open access: yesEndocrinology Research and Practice, 2013
Vitamin D is suggested to be an important immune system regulator. 1,25 dihydroxyvitamin D (1,25(OH)2D3), which is the active form of vitamin D, decreases the proliferation of purified T-helper (Th)1 cells as well as the production of interferon (IFN)??,

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Illuminating T cell-dendritic cell interactions in vivo by FlAsHing antigens

open access: yeseLife
Delineating the complex network of interactions between antigen-specific T cells and antigen presenting cells (APCs) is crucial for effective precision therapies against cancer, chronic infections, and autoimmunity.

T cell development and T cell responses in mice with mutations affecting tyrosines 292 or 315 of the ZAP-70 protein tyrosine kinase [PDF]

open access: yes, 2001
After stimulation of the T cell receptor (TCR), the tyrosine residues 292 and 315 in interdomain B of the protein tyrosine kinase ZAP-70 become phosphorylated and plausibly function as docking sites for Cbl and Vav1, respectively. The two latter proteins

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

T cell epitope engineering: an avian H7N9 influenza vaccine strategy for pandemic preparedness and response

open access: yesHuman Vaccines & Immunotherapeutics, 2018
The delayed availability of vaccine during the 2009 H1N1 influenza pandemic created a sense of urgency to better prepare for the next influenza pandemic.
