Q

Tell me about what produce from their lineage and what activate them to do the function for the following:
Natural killer cells
Mast cell
Esinophile

A

Nk cell is activated by il2 and il12 and inf alpha and beta it is activated by binding igG that is cross linked with the viral ag with the fcgammar111 ( unlike mast cell fc receptor)
Mast cell from the myeloid lineage by il3 and il4 by th2 and has a receptor for the ige that bind to it before the cross linking with the ag but not activated ( the mast cell) till ag bound to it it produces cytokines like tnf and il4 for th2 activation and il3 and il5 for esinophile production also activated by the anaphylatoxic complement
Esinophile production mentioned earlier and activation by chemokines and sometimes fc receptor bound to it ige same way as the mast cell

Q

Mention all of the opsinon

A

Complement (c3b c3dg with the receptor cr1 cr3 cr4 on the phagocytic cell)
Soluble ig ( not the membrane on that works as receptor)
C reactive p
Collectin ( considered humoral secreted pattern recognition molecules in the innate immunity)

12
Q

CpG drug

A

It triggers tlr 9 that will produce il12 and activate th1 with binding it to vaccines will treat cancer and activate lymphocyte
Remember th cell 2 just in esinophile and mast cell

il8 tnf
il8 and il1 tnf
il1 il6 and tnf
il2 il12 inf1
il3 il4
il3 il5
il12 tnf
Inf2 and th1

A

By T suppressor cells
Deep living keratinocytes
Macrophage for neutrophils recrutiment
Macrophage for helping liver produce crp
Activat nk cells
Production of mast cell by th2
Produced by th2 and mast cell for the production of esinophile
By macrophage to help in activation of macrophage
Receive them macrophage to help in costimulation of the adaptive immunity

Q

Mast cell is always stuck in tissue never seen in blood
Neutrophils is always in blood till infection occur
Macrophage is always in tissue and the tissue could be blood regardless there is infection or not

A

All of them are true

17
Q

Complement and opsinon
Complement and cell activator
Complement and chemotactic factor

A

C3b c3dg
C3dg
C3a c4a c5a

18
Q

Interferon induce enzyme synthesis in the target cell

A

True

19
Q

Could nk cell be activated by interferon gamma that is produced by

A

Yes surely and it’s written the sheet obviously

20
Q

The most important cytokines against mycobacterium tuberculosis

A

Il10

21
Q

Note question 90 and 95 on the lecture4 mcqs

A

Done

22
Q

What happens first if tissue is injured cytokines release or neutrophils influx

A

Cytokines release that lead to neutrophils influx

23
Q

NRLs represent which receptor in the innate immunity

A

Pattern recognition receptor
