The phenomenon of mitochondria donation is found in various tissues of humans and animals and is attracting increasing attention. To date, numerous studies have described the transfer of mitochondria from stem cells to injured cells, leading to increased

Disruption of HOX activity leads to cell death that can be enhanced by the interference of iron uptake in malignant B cells. [PDF]
The HOX genes encode a family of transcription factors that are dysregulated in several malignancies and have been implicated in oncogenesis and cancer cell survival.

Soluble CD40 ligand can replace the normal T cell-derived CD40 ligand signal to B cells in T cell-dependent activation [PDF]
We have constructed a soluble chimeric fusion protein between the mouse CD8 alpha chain and the mouse CD40 T cell ligand. This protein binds to both human and mouse B cells.

Pheromone-induced polarization is dependent on the Fus3p MAPK acting through the formin Bni1p [PDF]
During mating, budding yeast cells reorient growth toward the highest concentration of pheromone. Bni1p, a formin homologue, is required for this polarized growth by facilitating cortical actin cable assembly.

Not all antibodies against SARS-CoV-2 inhibit viral entry, and hence, infection. Neutralizing antibodies are more likely to reflect real immunity; however, certain tests investigate protein/protein interaction rather than the fusion event.

Distinct Requirements for HIV-Cell Fusion and HIV-mediated Cell-Cell Fusion [PDF]
Whether HIV-1 enters cells by fusing with the plasma membrane or with endosomes is a subject of active debate. The ability of HIV-1 to mediate fusion between adjacent cells, a process referred to as "fusion-from-without" (FFWO), shows that this virus can fuse with the plasma membrane.

MacroH2A histone variants have functions in differentiation, somatic cell reprogramming and cancer. However, at present, it is not clear how macroH2As affect gene regulation to exert these functions.

Two cellular models for analyzing mitochondrial heteroplasmy [PDF]
Aim: Mitochondria are essential for brain development, and the presence of different mitochondrial types is called mitochondrial heteroplasmy. Mitochondrial dysfunction is a central aspect of many people’s neurological diseases.

Structural Basis of Eukaryotic Cell-Cell Fusion [PDF]
Cell-cell fusion proteins are essential in development. Here we show that the C. elegans cell-cell fusion protein EFF-1 is structurally homologous to viral class II fusion proteins. The 2.6 Å crystal structure of the EFF-1 trimer displays the same 3D fold and quaternary conformation of postfusion class II viral fusion proteins, although it lacks a ...

A novel fusogenic herpes simplex virus for oncolytic virotherapy of squamous cell carcinoma
Background R849 is a neurovirulent γ134.5 gene-deficient form of herpes simplex virus type 1 (HSV-1) and has LacZ genes at the deleted sites of the γ134.5 gene. HF is a spontaneously occurring, fusogenic HSV-1 strain.
