Protein molecules are the molecules that set off an allergic reaction. Common allergens associated with protein molecules include pollen, dust mites and peanuts.
Allergents are antigens that cause an allergic reaction
Histamine is the small molecule that can cause an allergic reaction. It is a compound released by immune cells in response to an allergen and triggers symptoms such as itching, sneezing, and swelling. Antihistamines are commonly used to alleviate these allergic reactions by blocking histamine's effects.
That's an allergic reaction to the smoke, but I doubt that an asthmatic person can be a smoker.
When a receptor is stimulated it triggers impulses in other neurons....hope this was helpful and correct
Allergic reactions are not typically a trigger for a vasovagal nerve reaction. However, there are a number of known triggers, as well as some unknown. Any type of nerve malfunction, stress, or pain can trigger a reaction, so the symptoms associated with an allergic reactions should not be ruled out entirely.
The allergic red blotchy rash from Cipro (ciprofloxacin) and not from Levofloxacin can be attributed to differences in their chemical structures and how individual bodies react to them. Cipro may contain specific components or metabolites that trigger an immune response in certain individuals, leading to an allergic reaction. In contrast, Levofloxacin might not contain these triggers, or the immune system may not recognize it as a threat, resulting in no allergic response. Each person's immune system is unique, which can lead to varying reactions to different medications.

An allergen is something that generates, causes or triggers allergic symptoms. If you are allergic to house dust, house dust is your allergen.
Spontaneous emission is the process where an atom or molecule transitions from a higher energy state to a lower energy state, emitting a photon in the process without any external stimulation. Stimulated emission occurs when an incoming photon triggers an atom or molecule already in an excited state to emit a second photon that has the same wavelength, phase, and direction as the incoming photon, resulting in the amplification of light.

Allergic contact dermatitis following skin contact with poison ivy would lead to a delayed hypersensitivity type IV reaction, characterized by redness, itching, swelling, and blistering of the skin. This reaction occurs when the immune system recognizes the toxic oil urushiol found in poison ivy as a harmful substance and triggers an inflammatory response.
When the concentration of solutes in the blood, especially sodium, increases, the thirst center in the brain is stimulated. This triggers the sensation of thirst, prompting an individual to drink fluids and restore the body's fluid balance.
