Phosphodiesterase degrades cAMP in the cell, leading to the inactivation of the response to a hormone. This enzyme is crucial in regulating signal transduction pathways by breaking down cAMP into AMP.
Allergen
Cyclic adenosine monophosphate (cAMP) and intracellular calcium are produced in response to hormonal activation of G proteins. These second messengers play key roles in transmitting signals inside the cell in response to hormone binding to cell surface receptors.
This is a pH indicator.
An antigen is a substance that produces an immune response in the body, typically by binding to specific antibodies or activating immune cells. This immune response is essential for recognizing and eliminating foreign substances such as pathogens.

Cytokines
Excess accumulations of substances in cells may lead to cellular injury due to toxicity, immune response, and/or taking up cellular space Characterized by: Excessive amounts of normal intracellular substance Characterized by: - Accumulation of abnormal substances secondary to faulty metabolism or synthesis - Accumulation of pigments or particles that cell is unable to degrade Common site of accumulation is liver
Cyclic AMP (cAMP) is often referred to as the second messenger in signal transduction pathways. It is a key component in mediating intracellular responses to extracellular signals such as hormones and neurotransmitters.
The extracellular spaces are protected by the humoral immune response, in which antibodies produced by B cells cause the destruction of extracellular microorganisms and prevent the spread of intracellular infections. This is often called antibody mediated immunity. This response is triggered by an antigen and usually requires helper T cells.

Immune cells can detect intracellular pathogens through pattern recognition receptors (PRRs) that recognize specific pathogen-associated molecular patterns (PAMPs). When PRRs on immune cells bind to PAMPs, it triggers a signaling cascade that activates the immune response against the intracellular pathogen. This process helps immune cells detect and respond to the presence of intracellular pathogens.
