Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors? Yale Attitude Change Approach The topic of persuasion has been one of the most extensively researched areas in social psychology...

Intratracheal instillations deliver solutes directly into the lungs. This procedure targets the delivery of the instillate into the distal regions of the lung, and is therefore often incorporated in studies aimed at studying alveoli. We provide a detailed survival protocol for performing intratracheal instillations in mice.

Transgenic mice have been extremely useful in ascribing physiological function to genes. As such, research in general, and functional studies of airway, in particular, have undergone a remarkable shift toward murine models. Here we provide protocols for in vitro trachea constriction studies to evaluate smooth muscle function in murine airway.

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
The main mechanistic advantage is that material enters below much of the upper respiratory tract, reducing the influence of that region on initial exposure. This directs the administered substance toward the bronchi and lungs, making the respiratory tissues the primary site for observing pathogen distribution, inflammation, tissue injury, or treatment-related effects in a controlled experiment.
Using a defined dose makes comparisons between experimental groups more interpretable. When the delivered amount is standardized, differences in pathogen distribution, inflammatory responses, tissue injury, or protection can be related more directly to the tested microorganism, vaccine, drug, or other substance rather than to major variation in exposure. This supports controlled evaluation of respiratory outcomes.
Tracheal administration can support measurement of both local and systemic immune responses. Local measurements address reactions in the respiratory tract, while systemic measurements show whether the exposure is associated with responses beyond the lungs. Considering both levels helps immunology studies assess whether an intervention produces airway-focused effects, broader immune consequences, or evidence of protection.
Compared with exposure that occurs through the upper respiratory tract, the Tracheal Route places the test material farther along the airway at the start of the experiment. That distinction can be important when the study aims to evaluate pulmonary effects directly, rather than allowing upper-airway passage to determine how much material reaches the lungs.
A basic experimental workflow uses a catheter or pipette to introduce a defined amount into the trachea. The selected microorganism, vaccine, drug, or test substance is administered through that instrument, after which investigators evaluate its movement toward the bronchi and lungs and measure the response relevant to the study. Standardized delivery enables group comparisons.
In infection research, this route helps model respiratory disease by placing microorganisms directly into the airway. Investigators can then examine where the pathogen distributes, how much inflammation develops, and whether tissue injury occurs. These observations provide a controlled framework for comparing infection conditions and assessing how an intervention changes pulmonary disease-related outcomes.
For vaccine studies, the Tracheal Route can be used to assess protection at the respiratory site as well as immune effects beyond it. Researchers may compare responses after administering a vaccine and then examining local and systemic immunity, pathogen distribution, inflammation, or tissue injury. These measurements help connect vaccine exposure with pulmonary protection and disease-related changes.
Pulmonary treatment research can use the route to evaluate whether a drug or other test substance produces effects in the lungs. Direct airway delivery supports targeted assessment of treatment-related outcomes alongside inflammation or tissue injury. This is useful when the research question concerns respiratory tissues specifically and requires a consistent exposure for comparison across experimental conditions.
