Bacterial Cell Culture at the Single-cell Level Inside Giant Vesicles

7.5K
We demonstrate single-cell culture of bacteria inside giant vesicles (GVs). GVs containing bacterial cells were prepared by the droplet transfer method and were immobilized on a supported membrane on a glass substrate for direct observation of bacterial growth. This approach may also be adaptable to other...

Synthesis of Compound Giant Unilamellar Vesicles: A Biomimetic Model of Nucleate Cells

1.0K
This article presents a method for preparing compound Giant Unilamellar Vesicles (cGUVs) with a vesicle-in-vesicle structure, with customized electrical conductivity in inner, annular, and outer regions. Electroformation synthesizes simple GUVs, which are transformed into stomatocytes and cGUVs via osmotic shock, providing a valuable model for studying the biophysics of nucleated...

Development and Identification of a Novel Subpopulation of Human Neutrophil-derived Giant Phagocytes In Vitro

15.9K
We describe here a method for obtaining and identifying a newly characterized subpopulation of neutrophil-derived giant phagocytes. These cells develop in culture from fresh human blood neutrophils, and are characterized by phagocytosis, autophagy, immensely large size, and extended lifespan. This method is essential to further investigate this unique neutrophil-derived...

Electrophysiological Recordings from the Giant Fiber Pathway of D. melanogaster

15.0K
The Giant Fiber System is a simple neuronal circuit of adult Drosophila melanogaster containing the largest neurons in the fly. We describe the protocol for monitoring synaptic transmission through this pathway by recording post synaptic potentials in dorsal longitudinal (DLM) and tergotrochanteral (TTM) muscles following direct stimulation of the Giant Fiber...

Area of Science:

  • Rheumatology
  • Immunology

Background:

  • Large-vessel vasculitis encompasses giant cell arteritis (GCA) and Takayasu arteritis (TA).
  • GCA typically affects individuals over 50, predominantly women, presenting with acute symptoms like headaches.
  • TA usually manifests in younger populations with systemic inflammation affecting the aorta and its branches.

Purpose of the Study:

  • To outline the diagnostic and therapeutic strategies for GCA and TA.
  • To highlight recent advancements in treatment, including novel biologic agents.

Main Methods:

  • Diagnosis of GCA relies on imaging, with histology as an optional confirmation.
  • Treatment of GCA involves initial oral prednisone, with tocilizumab (TCZ) demonstrating high efficacy.
  • TA management includes steroids, disease-modifying antirheumatic drugs, and biologics like infliximab or TCZ.

Main Results:

  • Tocilizumab (TCZ) is highly effective for GCA treatment, offering an alternative to or adjunct with steroids.
  • Methotrexate can be used as a steroid-sparing agent in GCA.
  • TA treatment involves a combination of therapies, including TCZ and infliximab.

Conclusions:

  • Prompt diagnosis and treatment are crucial for GCA to prevent complications like blindness.
  • Both GCA and TA require tailored treatment approaches, with biologics like TCZ offering new therapeutic avenues.
  • Understanding the distinct clinical presentations and treatment responses is key for managing these large-vessel vasculitides.
