The adaptive immune system is activated before the innate immune system in response to a new pathogen.

The first line of defense against pathogens relies solely on cellular responses to eliminate threats.

Innate immunity is characterized by its ability to recognize specific antigens on pathogens through gene rearrangement.

Adaptive immunity is capable of immunological memory, leading to a faster and stronger response upon subsequent encounters with the same antigen.

Inflammation serves to exacerbate tissue damage by promoting the release of cytotoxic mediators without limiting the spread of pathogens.

Neutrophils, as early responders to infection, are long-lived cells that persist in tissues for extended periods to provide ongoing surveillance.

Pattern Recognition Receptors (PRRs) are germline-encoded and recognize pathogen-associated molecular patterns (PAMPs), leading to an immediate immune response.

Mannose-binding lectin (MBL) is a cell-surface receptor that directly binds to pathogens, initiating phagocytosis.

Toll-like receptors (TLRs) exclusively function on the cell surface to recognize extracellular pathogens, limiting their ability to detect intracellular threats.

Cytokines, which mediate inflammatory responses, are produced exclusively by immune cells and have limited impact on other physiological processes.

Interferons (IFNs) are a category of cytokines exclusively responsible for regulating antibody production.

Activation of the complement system leads exclusively to pathogen lysis and does not influence other immune functions.

Activated complement proteins contribute to pathogen recognition by directly binding to specific antigens on the pathogen surface.

Adhesion molecules are present exclusively on immune cells and play a limited role in promoting cell-cell interactions within the immune system.

Dendritic cells (DCs) are unique in their ability to migrate from infected tissues to lymph nodes, initiating the adaptive immune response by activating T cells.

The specificity of the adaptive immune response is achieved through germline-encoded receptors that recognize conserved pathogen-associated molecular patterns.

T helper cells directly kill infected cells by releasing cytotoxic granules, similar to cytotoxic T lymphocytes (CTLs).

The T-cell receptor (TCR) recognizes intact antigens directly, similar to how B-cell receptors (BCRs) recognize antigens

Memory lymphocytes always give lifelong immunity after initial exposure to an antigen.

Autoimmunity arises when the immune system fails to distinguish between self and non-self, leading to immune responses against the body's own tissues.
