Background: Semaphorin-3A (Sema3A) and Semaphorin-7A (Sema7A) play crucial roles in immune system by inhibiting T cell proliferation and leading to the secretion of pro-inflammatory cytokines.

Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia.

The Chemorepulsive Protein Semaphorin 3A and Perineuronal Net-Mediated Plasticity [PDF]
During postnatal development, closure of critical periods coincides with the appearance of extracellular matrix structures, called perineuronal nets (PNN), around various neuronal populations throughout the brain.

Expression of semaphorin-3A in the joint and role in osteoarthritis.
Osteoarthritis (OA) is characterised by the deterioration of cartilage in the joints and pain. We hypothesise that semaphorin-3A (sema-3A), a chemorepellent for sensory nerves, plays a role in joint degradation and pain.

The role of semaphorin 3A on chondrogenic differentiation. [PDF]
AbstractOsteoblast-derived semaphorin3A (Sema3A) has been reported to be involved in bone protection, and Sema3A knockout mice have been reported to exhibit chondrodysplasia. From these reports, Sema3A is considered to be involved in chondrogenic differentiation and skeletal formation, but there are many unclear points about its function and mechanism ...

Semaphorin 3A in the Immune System: Twenty Years of Study. [PDF]
Semaphorin 3A is a secreted glycoprotein, which was originally identified as axon guidance factor in the neuronal system, but it also possesses immunoregulatory properties. Here, the effect of semaphorin 3A on T-lymphocytes, myeloid dendritic cells and macrophages is systematically analyzed on the bases of all publications available in the literature ...

A Potential Role of Semaphorin 3A during Orthodontic Tooth Movement. [PDF]
Background: Induced tooth movement during orthodontic therapy requires mechano-induced bone remodeling. Besides various cytokines and growth-factors, neuronal guidance molecules gained attention for their roles in bone homeostasis and thus, potential ...

Activity-induced secretion of semaphorin 3A mediates learning. [PDF]
Abstract The semaphorin family is a well‐characterized family of secreted or membrane‐bound proteins that are involved in activity‐independent neurodevelopmental processes, such as axon guidance, cell migration, and immune functions. Although semaphorins have recently been demonstrated to regulate activity‐dependent synaptic scaling ...

Semaphorins in Adult Nervous System Plasticity and Disease
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.

The Role of Semaphorin 3A in Bone Remodeling [PDF]
Bone remodeling occurs at the bone surface throughout adult life and associates bony quantity and quality. This process is a balance between the osteoblastic bone formation and osteoclastic bone resorption, which cross-talks together. Semaphorin 3A is a membrane-associated secreted protein and regarded as a diffusible axonal chemorepellent, which has ...
