1 The argument that acquired immunity may bias the measurement of parasite resistance or limit the progression of those parasites deserves comment.

2 Acquired immunity functions here mean those new powerful defense capabilities produced by a certain factor inducement or participation on the basis of organism congenital structures and functions.

3 Objective:To compare the functions of natural immunity and acquired immunity in patients with primary gallbladder carcinoma (PGC) before operation after operation.

4 Acquired immunity, adaptable cytoprotection and RNA interference are organism acquired defense functions.

5 Acquired immunity relies on the long-term survival of sensitized T and B memory cells, which can proliferate quickly upon reinfection by the same pathogen.

6 These gene products control innate immune responses and further instruct development of antigen-specific acquired immunity.

7 By the time an African child enters school they have generally been repeatedly infected with malaria and have acquired immunity to the parasite making them less likely to die.

8 We then consider how this relationship may be modified by naturally acquired immunity, or by vaccination.

9 Objective:To provide the objective basis for prevention and treatment for the HBV infects, the infection sera modes of HBVA and the acquired immunity state of the health crowd were investigated.

10 Autophagy is an evolutionary cell mechanism, which not only assists the cell to adapt to a variety of metabolic stress, but also is involved in innate immunity and acquired immunity process.

11 The present paper deals with the biology of the parasitic copepod Lernaea poly-morpha and the acquired immunity on the part of the hosts after its infeetion on silver carp and big-head.

12 Lymphocyte: Type of leukocyte fundamental to the immune system, regulating and participating in acquired immunity.

13 The bacterial pathogens confront innate im-munity firstly when they invade host followed by acquired immunity. Both of them play defensive funtion to eliminish the invasive bacteria.
