The Relationship Between Immune Semaphorins and Myasthenia Gravis [PDF]

open access: yesBrain and Behavior
Objective Myasthenia gravis (MG) is an autoimmune disease involving several immune mechanisms. Recently, semaphorins have emerged as potential diagnostic and prognostic biomarkers in autoimmune neurological and non‐neurological diseases.

Semaphorins in Adult Nervous System Plasticity and Disease

open access: yesFrontiers in Synaptic Neuroscience, 2021
Semaphorins, originally discovered as guidance cues for developing axons, are involved in many processes that shape the nervous system during development, from neuronal proliferation and migration to neuritogenesis and synapse formation.

Association of Immune Semaphorins with COVID-19 Severity and Outcomes

open access: yesBiomedicines, 2023
Semaphorins have recently been recognized as crucial modulators of immune responses. In the pathogenesis of COVID-19, the activation of immune responses is the key factor in the development of severe disease. This study aimed to determine the association

Semaphorin-7A is an erythrocyte receptor for P. falciparum merozoite-specific TRAP homolog, MTRAP.

open access: yesPLoS Pathogens, 2012
The motility and invasion of Plasmodium parasites is believed to require a cytoplasmic actin-myosin motor associated with a cell surface ligand belonging to the TRAP (thrombospondin-related anonymous protein) family.

Do Semaphorins Play a Role in Development of Fibrosis in Patients with Nonalcoholic Fatty Liver Disease?

open access: yesBiomedicines, 2022
Nonalcoholic fatty liver disease (NAFLD) is associated with systemic changes in immune response linked with chronic low-grade inflammation and disease progression.

The olfactory critical period is determined by activity-dependent Sema7A/PlxnC1 signaling within glomeruli

open access: yeseLife, 2021
In mice, early exposure to environmental odors affects social behaviors later in life. A signaling molecule, Semaphorin 7A (Sema7A), is induced in the odor-responding olfactory sensory neurons.

Sema7A/PlxnCl signaling triggers activity-dependent olfactory synapse formation

open access: yesNature Communications, 2018
The molecular mechanisms underlying synapse formation in the olfactory bulb are not fully understood. Here the authors demonstrate that semaphorin 7A on olfactory sensory neurons, and its receptor plexin C1 expressed on mitral and tufted cells, is ...

Primary Membranous Nephropathy With Enhanced Staining of Exostosin 1/Exostosin 2 in the Glomeruli: A Report of 2 Cases

open access: yesKidney Medicine, 2021
Technological advances have allowed the discovery of 6 subtypes of membranous nephropathy based on target antigens: M-type phospholipase A2 receptor (PLA2R), thrombospondin type 1 domain-containing 7A (THSD7A), neural epidermal growth factor-like 1 ...

Signaling mechanisms of the platelet glycoprotein Ib-IX complex

open access: yesPlatelets, 2022
The glycoprotein Ib–IX (GPIb-IX) complex mediates initial platelet adhesion to von Willebrand factor (VWF) immobilized on subendothelial matrix and endothelial surfaces, and transmits VWF binding-induced signals to stimulate platelet activation.
