The ability to suppress immune function
Which cytokine is known for its role in controlling inflammation?
All of the above
Interferon-gamma

Interleukin-1
What is a key feature of innate immunity?
Requires prior exposure to pathogens
Provides a specific response
Acts as the first line of defense
Involves only B cells
What happens to B cell levels in ESRD patients?
They increase significantly
They remain unchanged
They are greatly reduced
They double in number
Which of the following is a characteristic of adaptive immunity?
Involves only physical barriers
Develops over time
Non-specific defense
Immediate response
What is the main function of chemokines in the immune system?
Direct cell movement
Activate immune cells
Produce antibodies
Enhance inflammation
How does the immune response change in CKD patients?
It is characterized by impaired responses
It remains unaffected
It becomes more efficient
It is enhanced by uremic toxins
What is the role of macrophages in the immune system?
Regulate blood pressure
Signal other immune cells
Engulf and kill microorganisms
Produce antibodies
Which immunoglobulin is primarily involved in allergic reactions?
IgA
IgM
IgE
IgG
What is the effect of oxidative stress on immune cells in CKD?
Enhances their function
Has no effect
Reduces their effectiveness
Increases their number
What is the significance of TLRs in the immune response?
They produce antibodies
They recognize pathogens
They regulate blood flow
They enhance oxygen delivery
Which of the following is a feature of adaptive immunity?
Memory response to previously encountered antigens
Non-specific defense
Immediate response to pathogens
Involves only innate cells
What is the primary function of interleukins in the immune system?
Transport oxygen
Regulate immune cell activity
Provide structural support
Enhance blood clotting
What is the impact of chronic inflammation on the immune system in CKD?
It has no impact
It enhances antibody production
It strengthens immune responses
It leads to immune dysfunction
Which type of immune response is primarily mediated by B cells?
Non-specific immunity
Innate immunity
Humoral immunity
Cell-mediated immunity
What is the role of helper T cells in the immune response?
Engulf pathogens
Directly kill infected cells
Assist other immune cells
Produce antibodies
What is a common consequence of impaired T-lymphocyte function in CKD?
Enhanced immune tolerance
Decreased inflammation
Higher infection rates
Increased vaccine efficacy
Which immunoglobulin is found in mucosal areas and secretions?
IgG
IgA
IgM
IgD
What is the effect of uremic toxins on neutrophil function?
Weakens their movement and germ-killing ability
Has no effect
Enhances their pathogen-killing ability
Increases their lifespan
What is the relationship between immunoglobulin levels and infection risk in CKD patients?
Higher levels lead to increased risk
No correlation exists
Higher levels reduce infection risk
Lower levels correlate with increased risk
What is the primary role of natural killer (NK) cells in the immune system?
Produce antibodies
Enhance inflammation
Kill virus-infected and tumor cells
Regulate blood pressure
What is the significance of the route of entry for antigens?
It has no effect on immune response
It only affects innate immunity
It determines the type of antibodies produced
It can influence the strength of the immune response
