GFAP serves as a structural element of tunneling nanotubes between glioblastoma cells and could play a role in the intercellular transfer of mitochondria.

Tunneling nanotubes (TNTs) are long F-actin-positive plasma membrane bridges connecting distant cells, allowing the intercellular transfer of cellular cargoes, and are found to be involved in glioblastoma (GBM) intercellular crosstalk. Glial fibrillary acid protein (GFAP) is a key intermediate filament protein of glial cells involved in cytoskeleton remodeling and linked to GBM progression. Whether GFAP plays a role in TNT structure and function in GBM is unknown.

Incidental Detection of Sarcomatoid Lung Cancer by [F] Choline Positron Emission Tomography/Computed Tomography.

A 79-year-old man treated for prostate cancer (PCa) in 2018 with concurrent hormone therapy and radical radiotherapy (RT) was given metastasis-directed RT because of skeletal progression of PCa in 2021. On [F]-choline positron emission tomography/computed tomography (CT) for biochemical recurrence (prostate-specific antigen level: 4.96 ng/mL), he showed significant uptake in multiple skeletal lesions and focal uptake in a left lung nodule.

Intercellular crosstalk mediated by tunneling nanotubes between central nervous system cells. What we need to advance.

Long-range intercellular communication between Central Nervous System (CNS) cells is an essential process for preserving CNS homeostasis. Paracrine signaling, extracellular vesicles, neurotransmitters and synapses are well-known mechanisms involved. A new form of intercellular crosstalk mechanism based on Tunneling Nanotubes (TNTs), suggests a new way to understand how neural cells interact with each other in controlling CNS functions.

is not decreased in symptomatic uncomplicated diverticular disease of the colon.

In this letter, assessment of the amount of fecal in symptomatic uncomplicated diverticular disease (SUDD) is described. Among 44 consecutive patients, comprising 15 SUDD patients, 13 patients with asymptomatic diverticulosis (AD), and 16 healthy controls (HC), the fecal amount of was not found to be significantly different between HC, AD and SUDD subjects (p=0.871).
