, Question 1
Explain the challenges of diagnosing autoimmune disorders.
Correct Answer
over 80 disorders, overlapping presentations, nonspecific manifestations that are seen in other non-autoimmune
diseases, blood testing isn't perfect as some are generic
Rationale:
Autoimmune disorders often present with overlapping symptoms and nonspecific manifestations that can be found in other non-
autoimmune diseases, making it difficult to accurately diagnose the specific condition. Additionally, blood testing may not be definitive
due to the generic nature of some tests, which can lead to false positives or false negatives, further complicating the diagnostic
process.
Question 2
which cell is first responder to phagocytose foreign invader
Correct Answer
monocyte
Rationale:
Monocytes are a type of white blood cell that circulates in the blood, positioning them to be the first in line to encounter foreign
invaders. Upon encountering an invader, monocytes rapidly mature into macrophages, allowing them to phagocytose and engulf the
foreign substance, effectively initiating the immune response.
Question 3
primary cells involved in adaptive immune response?
Correct Answer
lymphocytes
Rationale:
Lymphocytes are the primary cells involved in the adaptive immune response because they have the unique ability to recognize and
remember specific antigens, allowing them to mount a targeted and specific response to future infections. This is achieved through the
process of clonal selection, where lymphocytes undergo rapid proliferation and differentiation into effector cells that can eliminate
infected cells or produce antibodies to neutralize pathogens.
Question 4
T lymphocytes produce what type of immunity?
Correct Answer
cell-mediated
Rationale:
T lymphocytes produce cell-mediated immunity because they directly interact with and destroy infected cells or produce chemical
signals that activate immune cells, such as macrophages and other T cells. This type of immunity involves cellular responses rather
than antibody-mediated responses, which are characteristic of B lymphocytes.
