During what period of life does the development of immunocompetence occur?
When the baby is born
When the immune system reacts appropriately to an antigen and homeostasis is maintained it is termed what?
Immunocompetence
What is the site where T cells gain immunocompetence?
T cells gain immunocompetence in the thymus, a specialized organ located in the chest. During their development in the thymus, T cells undergo processes such as positive and negative selection to ensure they can effectively recognize foreign antigens while remaining tolerant to self-antigens. This maturation process is crucial for the formation of a functional adaptive immune response. Once fully matured, T cells migrate to peripheral tissues to carry out their immune functions.
What programs t cells for immunocompetence?
T cells are programmed for immunocompetence primarily in the thymus, where they undergo maturation and selection processes. During positive selection, T cells that can recognize self-MHC molecules with moderate affinity survive, while those that cannot are eliminated. Negative selection then removes T cells that bind too strongly to self-antigens, ensuring self-tolerance. This dual selection process is crucial for producing a functional T cell repertoire capable of responding effectively to pathogens while minimizing autoimmune responses.
Where do B lymphocytes develop immunocompetence?
Both type of lymphocytes are made in the bone marrow and only the B - Lymphocytes mature in the bone marrow, whereas the T Lymphocytes travel to the thymus gland where they mature.
When do lymphocytes become immunocompetent?
each lymphocyte must become able (competent) to recognize its one specific antigen bye binding to it. this ability is called immunocompetence.
What symptoms are caused by cat bites?
Cat bites are mostly found on the arms and hands. Sharp cat teeth typically leave behind a deep puncture wound that can reach muscles, tendons, and bones, which are vulnerable to infection because of their comparatively poor blood supply.
B lymphocytes develop immunocompetence in the?
Directly from my anatomy and physiology book - Marieb & Hoehn Eighth Edition: "Lymphocytes originate in red bone marrow from hematopoietic stem cells." " B cells become immunocompetent and self-tolerant in the bone marrow."
What is PHA found in cattle?
Pulmonary Hypoplasia with Anasarca This is a lethal genetic disorder that occurs in breeds like Simmental, Shorthorn, Maine Anjou and even in crossbred cattle. In laymen's terms, it means poorly formed, very small longs and excess retinal fluid, respectively. A calf that is born with PHA is very often born dead, or if born alive it dies shortly after.
Can you get the Swine Flu after you have taken the vaccine?
According to the Centers for Disease Control and Prevention: "The effectiveness of inactivated influenza vaccine depends primarily on the age and immunocompetence of the vaccine recipient, and the degree of similarity between the viruses in the vaccine and those in circulation."It is possible to get the swine flu even after taking a swine flu vaccination due to the above factors, and due to several other possible reasons:You had it already before you got the vaccine and just had not shown symptoms yet; or,between the time you took the vaccination and your body developed the full immunity (this can take as long as two weeks, but with the 2009 Swine flu vaccine it is expected to be only 8 - 10 days for healthy adults), you caught the flu; or,you may have caught a strain of flu that was different than the strain that was included in the vaccine, and so the vaccination would not provide immunity to the other strain. This can happen when there are mutations that significantly change the flu strain; or,because vaccines are not 100% effective in all people. For example, the 2009 seasonal flu vaccine was found in clinical trials to be expected to reduce laboratory-confirmed influenza by approximately 70% to 90% in healthy adults
