Designed Biomaterial‐Enhanced Cell Transplantation for Neural Tissue Engineering

Aggregate, EarlyView.
Biomaterials offer a promising solution for cell transplantation in the central nervous system by creating a protective environment that enhances cell survival, integration, and functional recovery in preclinical models of neurological disorders. ABSTRACT Cell transplantation therapy in the central nervous system is hindered by limited survival and ...

The dendritic cell synapse: a life dedicated to T cell activation

Frontiers in Immunology, 2016
T cell activation within immunological synapses is a complex process whereby different types of signals are transmitted from antigen presenting cells to T cells.

Interplay between membrane elasticity and active cytoskeleton forces regulates the aggregation dynamics of the immunological synapse [PDF]

Soft Matter 13, 6938 (2017), 2017
Adhesion between a T cell and an antigen presenting cell is achieved by TCR-pMHC and LFA1-ICAM1 protein complexes. These segregate to form a special pattern, known as the immunological synapse (IS), consisting of a central quasi-circular domain of TCR-pMHC bonds surrounded by a peripheral domain of LFA1-ICAM1 complexes.

TP53‐Mutated Myeloid Neoplasms: 2024 Update on Diagnosis, Risk‐Stratification, and Management

American Journal of Hematology, EarlyView.
ABSTRACT Alterations in the tumor suppressor gene TP53 are common in human cancers and are associated with an aggressive nature. Approximately 8%–12% of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) harbor TP53 mutations (TP53mut) and present immense challenges due to inherent chemoresistance and poor outcomes.

Modulation of Tumor Immunity by Soluble and Membrane-Bound Molecules at the Immunological Synapse

Clinical and Developmental Immunology, 2013
To circumvent pathology caused by infectious microbes and tumor growth, the host immune system must constantly clear harmful microorganisms and potentially malignant transformed cells. This task is accomplished in part by T-cells, which can directly kill

Dendritic Cells and HIV-1 Trans-Infection

Viruses, 2010
Dendritic cells initiate and sustain immune responses by migrating to sites of pathogenic insult, transporting antigens to lymphoid tissues and signaling immune specific activation of T cells through the formation of the immunological synapse.

Immunological recognition by artificial neural networks [PDF]

, 2018
The binding affinity between the T-cell receptors (TCRs) and antigenic peptides mainly determines immunological recognition. It is not a trivial task that T cells identify the digital sequences of peptide amino acids by simply relying on the integrated binding affinity between TCRs and antigenic peptides. To address this problem, we examine whether the

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

Imaging Membrane Curvature inside a FcεRI-Centric Synapse in RBL-2H3 Cells Using TIRF Microscopy with Polarized Excitation

Journal of Imaging, 2019
Total internal reflection fluorescence microscopy with polarized excitation (P-TIRF) can be used to image nanoscale curvature phenomena in live cells. We used P-TIRF to visualize rat basophilic leukemia cells (RBL-2H3 cells) primed with fluorescent anti ...

Krüppel‐like factor 4 transcription factor in blood–brain barrier endothelial cells: A potential role in Alzheimer's disease

Animal Models and Experimental Medicine, EarlyView.
KLF4 (Krüppel‐like factor 4) plays a protective role in blood–brain barrier (BBB). KLF4 plays an ambiguous role in the central nervous system. KLF4 in the BBB endothelial cells could be a potential target for Alzheimer's disease. Abstract Alzheimer's disease is the most prevalent chronic neurodegenerative disorder worldwide, with no sufficient cure ...
