The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.
A new example of niche formation, revealing the mode of niche cell migration, implicates extrinsic sources of positional information, and uncovers the pathway required for stereotypical positioning of the niche.

Cell biological study reveals the mechanism by which multiple satellite-DNA-binding proteins cooperate to form chromocenter to encapsulate the full complement of chromosomes.
ICOSL-dependent T-cell co-stimulation contributes to the host defense against herpesvirus infections, and accordingly, these pathogens have developed immune evasion mechanisms to interrupt the ICOSL:ICOS signaling pathway.
A critical analysis of recent single-cell transcriptomic studies of Drosophila blood cells confirms the extreme plasticity of the major phagocyte class, identifies a new class of blood cell, and suggests relationships to blood cells in other insects.
Ribosomal proteins Rps27 (eS27) and Rps27l (eS27L) are an ancient pair of duplicated genes that encode functionally interchangeable proteins, yet have been evolutionarily retained because both copies are necessary to achieve protein expression across cell types.

A distinct resident macrophage subpopulation that localizes to the adipose stroma and fibrous capsule of the nulliparous mammary gland and to extracellular matrix-enriched stroma surrounding mammary tumors is identified.
3D culture of breast cancer in biologically relevant ECM potentiates the growth-inhibitory effects of unacylated ghrelin and AZP-531, and clinical response may be predictable based on a MAPK gene signature.
