Added 8152015 110907 AM. This answer has been confirmed as correct and helpful. E A B and C are correct.

A A TH cell acts as an antigen-presenting cell for the T-dependent antigen. AOnly requires interaction between MHC molecule of an antigen presenting cell APC with the appropriate T cell receptor. Most antigens have a large molecular weight and are chemically composed of proteins or polysaccharides but may also be lipids polypeptides or nuclear acids among others.

They are not bound to the cell membrane. Which of the following statements about T-dependent antigens is true. They usually cause cellular damage.

Antibodies to Lewis antigens rarely cross the placenta. 22 The following is true of histo-blood group antigens. Solve it within 10 mins Ill give you multiple upvote.

CRequires both A and B. An example would be the ABO blood. BOnly requires the binding of the B7 protein on the antigen presenting cell APC with the appropriate T cell receptor.

D all immunogens are proteins and all proteins are immunogens. Which of the following is TRUE about antigens. Antigens are produced by the body in response to a foreign invader.

Antigens are typically composed of nucleotides. They have immunogenicity which means they provoke immune responses b. Antigens are limited to one antigenic determinant per antigen molecule.

They are recognized by T cells or B cells. Lymph nodes are found in villi of small intestines note micro villi. They are always derived from pathogens.

21 Which of the following is not involved in the expression of the B antigen. Which of the following is true of antigens. B Are usually of less than 10 kD in molecular weight.

Antibodies are secreted and function away from the cell. View the full answer. A Antigen in lymph entering them can active res.

Which of the following statements is true Options All immunogens are antigens but all antigens are not immunogens All immunogens are antigens and all antigens are immunogens All immunogens are not antigens but all antigens are immunogens All immunogens are proteins. They are specific to pathogens. They are often large protein molecules d.

C all immunogens are not antigens but all antigens are immunogens. Which of the following is characteristic of antigens. C Alone are always capable of stimulating specific immune responses.

B include type I antigens which are found on virtually all nucleated cells in the body. Lewis antigens are found on type II precursor chains b. Found only on the red blood cell membrane.

They are always proteins. 18 Right answer is c they are found in microvilli of the small intestine as a lacteal Explanations. Which of the following is not true about the antigens.

Antibodies to Lewis antigens always cause HTRs d. They always invade the human body from the external environment e. Are also called Erythroid-specific proteins.

Antigens are substances that activate the adaptive immune response. 26 MHC antigens A are self-antigens. Choose more than one a Can only be polysaccharide in nature.

They have reactivity which means they react with the antibodies or cells they provoked c. Galactose N-acetylgalactosamine fucosyltransferase glycosyltransferase None of the above. A molecular weight of at least 8 000 to 10 000 Da however it must be noted that haptens of only 200 Da molecular weight have been conjugated with a carrier protein Can undergo processing by the immune system.

Antibodies have multiple antigen binding sites. Antibodies are built from equal number of large heavy and small light chains. C include type II antigens which are found only on activated antigen presenting cells.

D CTL cells are required for the activation process.
