Expression and Function of Transmembrane-4 Superfamily (Tetraspanin) Proteins in Osteoclasts: Reciprocal Roles of Tspan-5 and NET-6 during Osteoclastogenesis

open access: yesAllergology International, 2007
Background: Osteoclasts are bone-resorbing multinuclear polykaryons essential for bone remodeling, formed through cell fusion of mononuclear macrophage/monocyte lineage precursor cells upon stimulation by the RANK/RANKL system.

Very Rare Complementation between Mitochondria Carrying Different Mitochondrial DNA Mutations Points to Intrinsic Genetic Autonomy of the Organelles in Cultured Human Cells [PDF]

open access: yes, 2000
In the present work, a large scale investigation was done regarding the capacity of cultured human cell lines (carrying in homoplasmic form either the mitochondrial tRNALys A8344G mutation associated with the myoclonic epilepsy and ragged red fiber ...

Cell fusion [PDF]

open access: yesWormBook, 2006
Selective cell fusion is a natural part of development. It is found in sexually reproducing organisms that require fertilization to propagate and in muscles, placenta, bones, lens of the eye and stem cells. Cell fusion is particularly important in the development of C. elegans: in addition to 300 sperm and oocytes that fuse during fertilization, 300 of

Requirement of myomaker-mediated stem cell fusion for skeletal muscle hypertrophy

open access: yeseLife, 2017
Fusion of skeletal muscle stem/progenitor cells is required for proper development and regeneration, however the significance of this process during adult muscle hypertrophy has not been explored.

Cell Fusion-Related Proteins and Signaling Pathways, and Their Roles in the Development and Progression of Cancer

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cell fusion is involved in many physiological and pathological processes, including gamete binding, and cancer development. The basic processes of cell fusion include membrane fusion, cytoplasmic mixing, and nuclear fusion.

Constructive role of dissipation for driven coupled bosonic modes [PDF]

open access: yes, 2008
We describe four cases of childhood B-cell progenitor acute lymphoblastic leukaemia (BCP-ALL) and one of T-cell (T-ALL) with unexpected numbers of interphase signals for ETV6 with an ETV6-RUNX1 fusion probe.

Generation of virus-specific cytotoxic T cells in vitro II. Induction requirements with functionally inactivated virus preparations [PDF]

open access: yes, 1980
Using noninfectious Sendai virus preparations after selective enzymatic digestion of either of the two viral envelope glycoproteins, it was possible to study the effect of different virion-cell membrane interactions on virus-specific cytotoxic T ...

Emerging functions of mammalian mitochondrial fusion and fission [PDF]

open access: yes, 2005
Mitochondria provide a myriad of services to the cell, including energy production, calcium buffering and regulation of apoptosis. How these diverse functions are coordinated among the hundreds of mitochondria in a given cell is largely unknown, but is ...

Mitochondrial fusion and Bid-mediated mitochondrial apoptosis are perturbed by alcohol with distinct dependence on its metabolism [PDF]

open access: yes, 2018
Environmental stressors like ethanol (EtOH) commonly target mitochondria to influence the cell’s fate. Recent literature supports that chronic EtOH exposure suppresses mitochondrial dynamics, central to quality control, and sensitizes mitochondrial ...
