1T cytoxic cells bear a receptor that is used to identify it

1.T cytoxic cells bear a receptor that is used to identify it distinctly from other immune cells. The receptor is know as cluster of differentiation CD-----------.

2. place the immunity concepts in order referencing basic immunity organization levels lines of Defense 1,2,3

A. HCL or Tears
B. Engulfing pathogens or Fever
C. Infected cell killing or immunoglobulin prosuction

3.Opsonizationot is best represented by this matching pair.

A. natural killer human cell with virus
B. Ts down regulate immune responses
C. B, cell Fc antibody class
D. neutrophils serrations marrescens
E. CD4+CXCR4 co-receptor binding and entry

4. what is the HIV protein that is involved in attachment of the virus to human immune cells?

5. identify the HIV antiviral drug that would stop the virus from exiting the helper Tcell.

isentres

retro vir

crixivan

mouse enzyme

selzentry

6. The maim type of immune cell infected by HIV are the -----------cells in the course of an infection.

7.All of the following are physical barriers to pathogens except

unbroken skin

mucous

hairs

tears

t cellso

8. B cells are activated by?

9. plasma cell best description?

function in cell mediated immunity

are derived from T lymphocytes

produce and secrete antibodies

responsible for making complement protein

10. when does the lectin pathway for the complement systems achieved it\'s goal

1. it begins with antibodies similar to the classical pathway

2. the goal happen during a lost of function

3. once C3 breaks a part the 3 goalso of the complement system begin

4. when complement protein B,D and        P , are attracted to the pathogen

Solution

1) Cluster of differentiation CD3, which exists in three forms gamma, Delta, epsilon which shows on the surface of the T cells which distinguish from the other cells invovled in the cell.mediated immune response.

2) a) stomach acid, mucus , tears, sweat , is the first line of defense which protects from outer entry of pathogen through chemical and physical barriers.

B) second line of defense when the cell of skin rupture it causes entry of the pathogens causes the macrophages, neutrophils to localise at the pathogen causes inflammation, fever response so that pathogen cannot multiply arrested to eradicate from host.

C) when pathogen entered into the body the immunoglobulin IgG recognises first, CD3 protein of complement system makes identification to elicit humoral and cell mediated immune response is the example of third line of defense mechanism.

3) C when the pathogen enters the B cells,FC receptors mediates to follow opsonisation , this mediated by the antibodies generated by the plasma cells thus antigen is presented and eradicated from the host.

4) HIV consists of the surface glycoprotein called gp120 which identifies the antigen so it acts as receptors.

5)D mouse enzyme isentress is used , to inhibit the exit of the virion from the T cells, it inhibits the integration of the viral DNA with The cell DNA so that multiplication is halted.

6) T cells is infected during course of HIV infection

7) t cells are not.physical barriers of immune system.

8)the b cell receptors recognises the antigens and process the to produce plasma cells and memory cells to produce antibodies

9) b cells activates and produces plasma cells and memory cells these antigen presented to the cells of immune system. Thus triggers and elicit neutralisation, opsonisation response.

10) 4 when the factor B , D are attracted by the pathogen, lectin binded to mannose , by cleavage of serine protease
