Calcium is a ubiquitous messenger in the nervous system, essential for triggering neurotransmitter release and changes in synaptic strength. Here we demonstrate a technique for loading Ca2+-indicators into Drosophila nerve terminals. We also demonstrate fabrication of the required apparatus and emphasize points critical for the technique's success.

Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Bradley Schmitz Fungi are heterotrophic eukaryotic organisms, and with the exception of yeasts, are aerobic. They are abundant in surface soils and are important for their role in nutrient cycling and the decomposition of organic matter and organic contaminants. White rot fungi (phanerochaete chryosporium) for example, (Figure 1) are known to degrade aromatics. Figure 1. White rot on...

Termination of Translation

2020
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Here, we present a method for light microscopy analysis of tracheal terminal cells in Drosophila larvae. This method allows for quick examination of branch and lumen morphology in whole animals and would be useful for analysis of individual mutants or screens for mutations affecting terminal cell development.

FAQs
During ovary development, terminal filament cells undergo coordinated changes in shape and organize into ordered stacks. Cell adhesion helps neighboring cells remain connected, while polarity establishes consistent spatial orientation and signaling coordinates these behaviors. Together, these processes produce a stable filament architecture rather than an unstructured collection of cells, making morphogenesis central to how the anterior ovary is assembled.
Their interactions with cap cells and germline stem cells link tissue structure to niche organization. Terminal filament cells help create a structural connection with neighboring cap cells and the germline stem cell niche, positioning somatic tissue alongside germline cells. This arrangement supports communication between the two cell populations and helps establish the local organization required for reproductive tissue development.
Terminal filament cells contribute to ovariole organization by helping define the architecture of the ovary’s functional egg-producing units. Their anterior position and interactions with adjacent somatic and germline cells influence how these units are arranged and connected. Consequently, their organization provides a useful context for investigating how tissue structure and somatic-germline communication support egg production.
Terminal filament cells are relevant because their development combines cell-shape changes, ordered assembly, adhesion, polarity, and signaling within a developing tissue. Examining how these features become coordinated helps explain epithelial morphogenesis, meaning the formation and organization of tissue structure. The same analysis also connects tissue architecture with the creation of a reproductive stem cell niche.
Studies of terminal filament cells can examine how somatic tissue establishes and maintains organization around germline cells. The key outcomes include understanding niche formation, communication between somatic and germline populations, and the developmental mechanisms that maintain reproductive tissues. This makes the cells useful for connecting local cellular interactions with larger-scale ovary and ovariole architecture.
In biology, these cells provide a focused system for asking how reproductive tissues are built through interactions among neighboring cell populations. Their position at the anterior ovary, connection to cap cells, and relationship to the germline stem cell niche allow researchers to relate cell arrangement to tissue function. This context is especially relevant to development and reproductive biology.
