Les Cellules Immunitaire đź”… Flashcards
Quelle est la fonction des cellules immunitaires ?
Les cellules immunitaires sont chargées d’identifier et d’éliminer les agents pathogènes et les substances étrangères dans l’organisme.
Nommez les deux principaux types de cellules immunitaires .
Les deux principaux types de cellules immunitaires sont les lymphocytes et les cellules myéloïdes.
Vrai ou faux : Les cellules T sont un type de lymphocyte.
Vrai.
Remplissez l’espace vide : Les cellules B sont responsables de la production de ______.
Les Anticorps.
Quel est le rôle des macrophages dans le système immunitaire ?
Les macrophages engloutissent et digèrent les agents pathogènes et les cellules mortes.
Quel type de cellule immunitaire est principalement impliqué dans la réponse immunitaire adaptative ?
Les lymphocytes, y compris les cellules T et les cellules B, sont principalement impliqués dans la réponse immunitaire adaptative.
Quelle est la fonction des cellules dendritiques ?
Les cellules dendritiques présentent des antigènes aux cellules T pour déclencher une réponse immunitaire.
Citez un type de cellule myéloïde.
Un type de cellule myéloïde est le neutrophile.
Vrai ou faux : Les cellules tueuses naturelles (NK) font partie du système immunitaire inné.
Vrai.
What is the primary function of neutrophils?
Neutrophils are primarily responsible for the rapid response to infection, particularly bacterial infections.
Describe the role of T helper cells.
T helper cells assist other immune cells by releasing cytokines.
Fill in the blank: Cytotoxic T cells are responsible for killing ______ infected cells.
virus.
What is the importance of memory cells?
Memory cells provide long-term immunity by remembering past infections.
True or False: Immune cells can communicate with each other through cytokines.
True.
What is the role of regulatory T cells?
Regulatory T cells help maintain immune tolerance and prevent autoimmune responses.
Name a key feature of the innate immune response.
The innate immune response is non-specific and immediate.
What do antigen-presenting cells do?
Antigen-presenting cells display antigens to T cells to activate them.
Fill in the blank: The immune system can distinguish between ______ and self-cells.
non-self.
What is the role of eosinophils?
Eosinophils are primarily involved in combating parasitic infections and allergic reactions.
True or False: All immune cells originate from stem cells in the bone marrow.
True.
What type of immune cell is primarily involved in allergic reactions?
Mast cells are primarily involved in allergic reactions.
Fill in the blank: The process of phagocytosis is performed by ______ cells.
phagocytic.
What is the function of the complement system?
The complement system enhances the ability of antibodies and phagocytes to clear pathogens.
Name one cytokine released by immune cells.
Interleukin-2 (IL-2) is an example of a cytokine.
What is the difference between innate and adaptive immunity?
Innate immunity is immediate and non-specific, while adaptive immunity is delayed and highly specific.
True or False: Immune cells can only be found in the blood.
False.
