Could you help with any of these ? and provide an explanation so I'll understand? thank you so much Circle all that apply 1) A patient has inherited two defective genes for TAP2 (remember the case study from before) Which of the following are true? (circle all that apply): - The patient will have a scarcity of CD4+ T helper cells -MHC class I molecules will not be expressed to any extent on the patient's cells -MHC class II molecules...
ANSWER ALL THE QUESTIONS FULLY AND CORRECTLY!!! 1) A patient has inherited two defective genes for TAP2 (remember the case study from before) Which of the following are true? (circle all that apply): - The patient will have a scarcity of CD4+ T helper cells -MHC class I molecules will not be expressed to any extent on the patient's cells -MHC class II molecules will be reduced in expression - The patient will have an impaired ability to fight viral...
QUESTION 1 Immature B cells whose BCRs are strongly activated by self antigens present in the bone marrow are induced to undergo receptor editing to change the specificity of their BCRs. True False QUESTION 2 MHC genes show codominant expression patterns, meaning any cell expressing that class of MHC molecules transcribes DNA from that genetic locus on both chromosomes in the pair (maternal and paternal) simultaneously. True False
Identify which of the following statements is true regarding the transporter associated with antigen processing (TAP) TAP is composed of three identical subunits TAP is a membrane-bound transport protein TAP transports proteasome-derived peptides from the cytosol directly to the lumen of the Golgi apparatus Peptides transported by TAP bind preferentially to MHC class II molecules Question 4 (2 points) All of the following are included in the peptide-loading complex except ERp57 B roglobu
