Which cell type is typically NOT associated with an inflammatory response?

Fibroblasts are not typically associated with an inflammatory response in the same way that neutrophils, lymphocytes, and eosinophils are. Inflammation is primarily characterized by the presence of immune cells that respond to injury or infection. Neutrophils are among the first responders to sites of inflammation, playing a critical role in the acute immune response. Lymphocytes are involved in the adaptive immune response and are also recruited during inflammation, particularly in chronic inflammatory conditions. Eosinophils are primarily involved in the response to parasitic infections and allergic reactions and can also be present during inflammation.

On the other hand, fibroblasts are connective tissue cells primarily responsible for the synthesis of extracellular matrix and collagen, contributing to tissue repair and healing rather than the immediate inflammatory response. Although fibroblasts may be indirectly involved in the healing process following inflammation, they are not characteristic cells of the inflammatory response itself.
