Cover: The in vitro reconstitution of a network of actin filaments. Filaments formed dense and branched meshworks (yellow) above micropatterned lipid bilayers on which they were nucleated. They formed a complex array of individual filaments and bundles (yellow and blue) in the space in between the micropatterned bars. See article by M. Gélin et al. (jcs261667).

RESEARCH HIGHLIGHTS
STICKY WICKET
CELL SCIENCE AT A GLANCE
Actin-based protrusions at a glance
Summary: In this Cell Science at a Glance poster, we summarize current knowledge of the functional and structural characterizations of actin-based protrusions, with a focus on filopodia, cytonemes and tunneling nanotubes.
REVIEW
Expanding roles of BCL-2 proteins in apoptosis execution and beyond
Summary: A review of the molecular mechanism of MOMP, with a focus on recently discovered roles of BCL-2 proteins in apoptosis and beyond, including what implications these might have in both healthy tissues and disease.
RESEARCH ARTICLES
The antiproliferative effect of FGF2 in K-Ras-driven tumor cells involves modulation of rRNA and the nucleolus
Summary: The antiproliferative effect of FGF2 in an oncogenic cell model modulates transcription, particularly rRNA expression, promotes nucleolus disorganization and directly modulates the proteome of the rDNA loci.
Human sperm rotate with a conserved direction during free swimming in four dimensions
Summary: We utilise the spherical aberration of the objective lens in bright-field imaging to reveal that the human spermatozoon head rotates in a counterclockwise direction, as viewed from head to tail.
Cholesterol regulates insulin-induced mTORC1 signaling
Summary: The insulin–mTORC1 growth axis is defective in individuals with SLOS, who have a cholesterol biosynthesis disorder. The defect can be corrected in cells by supplementing cholesterol or by activating Rag GTPase.
Structure and dynamics of the contractile vacuole complex in Tetrahymena thermophila
Highlighted Article: In the ciliate Tetrahymena thermophila, four proteins are shown to provide markers for different zones of the contractile vacuole complex and, hence, enable in vivo analysis of its dynamics.
Microtubules under mechanical pressure can breach dense actin networks
Highlighted Article: Microtubules under mechanical pressure can breach dense actin networks solely based on their polymerization forces. Mechanical pressure can be induced by mechanical hindrance or by using crosslinkers.
Cholesterol is required for activity-dependent synaptic growth
Highlighted Article: Changes in the cholesterol content of presynaptic terminals play critical roles in the development and plasticity of Drosophila larval neuromuscular junctions.
TOOLS AND RESOURCES
Pre-gelation staining expansion microscopy for visualisation of the Plasmodium liver stage
Summary: A protocol for investigating the Plasmodium liver stage that involves the expansion of pre-stained samples, leading to a significantly expedited procedure, and enhanced preservation of specific epitopes.

Intermediate filaments at a glance
Although intermediate filaments are known for their structural support, emerging evidence reveals their involvement in various cellular processes, underscoring their significance in disease development and progression. In this Cell Science at a Glance article, Leila Coelho-Rato and colleagues discuss the established classes of intermediate filaments and their general features, their functions beyond structural support and recent advances in the field.
