Exam 13: Host Defenses II: Specific Immunity and Immunization

After secreting antibodies during an immune response,plasma cells then differentiate into memory cells.

T-cell response to T-cell-dependent antigens requires ________.

Which process involves antibodies cross-linking cells or particles into large aggregates?

Which process involves antibodies coating microorganisms in order to facilitate phagocytosis?

A 2-week-old infant is brought to a family practice office for a scheduled visit. The parents appear anxious, as this is their first child. They express multiple concerns to the nurse about their son's sleep patterns, feeding, and crying. The RN provides empathetic listening and education to calm their fears, and they are receptive to the teaching. When the RN discusses vaccination with the parents, they refuse to vaccinate their son because they have heard vaccines can cause autism in children. -Following education from the RN,the parents decide to have their son vaccinated.Which of the following is the most important part of the family history to elicit?  

Herd immunity involves ________.

Lymphocytes ________.

Which process involves a more rapid synthesis and greatly increased titer of antibody when the immune system is subsequently exposed to the same antigen?

Gamma-delta T cells differ from other T cells in that ________.

The hinge region of an antibody has a hypervariable amino acid region where the antigenic determinant fits.

A 6-year-old male is brought to his pediatrician's office with chickenpox. He has had symptoms for one week, and his mother is concerned about the patient's 8-year-old sister because she had a long, painful chickenpox infection 2 years prior. Of note, the patient was not vaccinated against chickenpox because his parents did not think it was a serious enough virus to warrant the pain of the injection. -Which form of acquired immunity is the patient developing by having this infection?  

Live,attenuated vaccines ________.

One plasma cell will secrete antibodies of various classes but the antibodies will all have the same specificity.

A 2-week-old infant is brought to a family practice office for a scheduled visit. The parents appear anxious, as this is their first child. They express multiple concerns to the nurse about their son's sleep patterns, feeding, and crying. The RN provides empathetic listening and education to calm their fears, and they are receptive to the teaching. When the RN discusses vaccination with the parents, they refuse to vaccinate their son because they have heard vaccines can cause autism in children. -What kind of immunity will be conferred to the infant through vaccination? 

The monomer subunit of immunoglobulin molecules has all the following except ________.

To exhibit high immunogenicity,an antigen would preferably________.

What type of cells secrete antibodies?

An example of natural passive immunity would be ________.

What process provides many B cells and T cells that are activated against specific antigens?

The structural and functional differences that distinguish immunoglobulin isotypes are due to variations associated with their Fc fragments.
