Here, we describe a new approach to inflict closed-head traumatic brain injury in Drosophila melanogaster. Our method has the advantage of directly delivering repetitive impacts with adjustable strength to the head alone. Further exploration of the invertebrate system will help to illuminate the pathogenesis of chronic traumatic encephalopathy.

2023
Drosophila melanogaster, also known as the fruit fly, is a powerful model organism widely used in biological research that has made significant contributions to the greater scientific community over the last century. First, this video introduces the fruit fly as an organism, including its physical characteristics, life cycle, environment, and diet. Next, the reasons why fruit flies make an excellent model organism are discussed. For example, fruit flies are inexpensive to maintain in the...

Drosophila Larval IHC

2023
Immunohistochemistry (IHC) is a technique used to visualize the presence and location of proteins within tissues. Drosophila larvae are particularly amenable to IHC because of the ease with which they can be processed for staining. Additionally, the larvae are transparent, meaning that some tissues can be visualized without the need for dissection. In IHC, proteins are ultimately detected with antibodies that specifically bind to “epitopes” within the protein of interest. In order to preserve...

Drosophila melanogaster, commonly known as fruit flies, are a frequently used model organism for life science research. Although starting a collection of these critters may seem as easy as leaving a banana on your kitchen counter for too long, a productive fly colony in the lab requires careful husbandry and maintenance. This video demonstrates the necessary steps for maintaining a healthy fly stock. The overview begins with the preparation and storage of the yeast and sugar-containing media on...

Drosophila Development and Reproduction

One of the many reasons that make Drosophila an extremely valuable organism is that the molecular, cellular, and genetic foundations of development are highly conserved between flies and higher eukaryotes such as humans. Drosophila progress through several developmental stages in a process known as the life cycle and each stage provides a unique platform for developmental research. This video introduces each stage of the Drosophila life cycle and details the physical characteristics and major...
FAQs
By selecting or introducing a mutation, researchers create a specific genetic change and then examine the resulting phenotype, or observable trait. Comparing altered flies with appropriate unaltered counterparts helps link a gene to a biological process. Following the trait across generations can further clarify inheritance patterns and strengthen conclusions about the gene’s role.
A controlled cross organizes which parental flies contribute genetic material to the next generation. Researchers can then observe how a selected or introduced mutation is transmitted and how its associated phenotype appears among offspring. Repeating observations across generations makes it possible to study inheritance systematically rather than relying on isolated individual differences.
Conserved cellular and molecular pathways allow findings from flies to inform questions about other animals, including mechanisms relevant to human disease. When an altered gene affects a pathway or phenotype in Drosophila, the result can provide a tractable biological system for investigating that process and identifying potential therapeutic targets.
A typical workflow begins by selecting or introducing a genetic mutation, followed by controlled crosses that generate offspring with defined genetic backgrounds. Researchers observe the resulting phenotypes at relevant developmental stages and compare patterns across generations. This sequence connects genetic manipulation with measurable biological outcomes and provides evidence for or against a proposed hypothesis.
The model supports investigations of development, behavior, neuroscience, and disease mechanisms in addition to genetics. Its defined developmental stages help researchers relate genetic changes to developmental outcomes, while observed behavioral or disease-related phenotypes can connect molecular alterations with broader biological effects. These applications make Drosophila relevant across several areas of biology.
Researchers can use disease-related genetic changes in flies to examine how altered genes affect biological processes and observable phenotypes. Because many cellular and molecular pathways are conserved between Drosophila and other animals, these experiments can support investigation of disease mechanisms and evaluation of potential therapeutic targets before broader biological testing.
