Involvement of microglia in chronic neuropathic pain associated with spinal cord injury - a systematic review.

Rev Neurosci

December 2023

Department of Biomedicine, Experimental Biology Unit, Department of Biomedicine, Faculty of Medicine of Porto, University of Porto, Alameda Prof. Hernâni Monteiro, 4200-319 Porto, Portugal.

In recent decade microglia have been found to have a central role in the development of chronic neuropathic pain after injury to the peripheral nervous system. It is widely accepted that peripheral nerve injury triggers microglial activation in the spinal cord, which contributes to heightened pain sensation and eventually chronic pain states. The contribution of microglia to chronic pain arising after injury to the central nervous system, such as spinal cord injury (SCI), has been less studied, but there is evidence supporting microglial contribution to central neuropathic pain.

A growing number of studies have shown that tumor cells secrete extracellular vesicles (EVs) containing programmed death-ligand 1 (PD-L1) protein. These vesicles can travel to lymph nodes and remotely inactivate T cells, thereby evading immune system attack. Therefore, the simultaneous detection of PD-L1 protein expression in cells and EVs is of great significance in guiding immunotherapy.

Apical-basal polarity of the spectrin cytoskeleton in the vulva.

MicroPubl Biol

June 2023

Department of Genetics, University of Pennsylvania, Philadelphia, Pennsylvania, United States.

The vulva is a polarized epithelial tube that has been studied extensively as a model for cell-cell signaling, cell fate specification, and tubulogenesis. Here we used endogenous fusions to show that the spectrin cytoskeleton is polarized in this organ, with conventional beta-spectrin ( UNC-70 ) found only at basolateral membranes and beta heavy spectrin ( SMA-1 ) found only at apical membranes. The sole alpha-spectrin ( SPC-1 ) is present at both locations but requires SMA-1 for its apical localization.

Infection with hypervirulent triggers emergency myelopoiesis but not trained immunity.

Front Immunol

July 2023

Instituto de Investigação e Inovação em Saúde (i3S), Universidade do Porto, Porto, Portugal.

Introduction: During infection, bone marrow (BM) hematopoiesis is reprogrammed toward myeloid cell production, a mechanism named emergency myelopoiesis. In addition to replenishing myeloid cells, emergency myelopoiesis has been linked to trained immunity, a process that allows enhanced innate immune responses to secondary challenges. Although hematopoietic alterations during tuberculosis (TB) have been described and may colonize the BM, studies using the mouse model of infection and the laboratory reference strain H37Rv have demonstrated limited emergency myelopoiesis and trained immunity.
