MODE FOR INVENTION
[0124] Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the following examples are provided only for illustration of the present invention and should not be construed as limiting the scope of the present invention.
Preparation Example 1
[0125] Histopaq 1077 was purchased from Sigma-Aldrich Corporation, and Brefeldin A was purchased from BioLegend Inc. As antibodies, Alexa 647 anti-IL-22 and PE anti-mouse IL-10R were purchased from BioLegend Inc., and PerCP mouse IL-22R was purchased from R & D. PBS (phosphate buffered solution) containing 0.5% bovine serum albumin (BSA) was used as a FACS buffer. A cell fixation buffer and a perm/wash buffer were also purchased from BioLegend Inc.
Example 1
[0126] 1. Isolation of Peripheral Blood Mononuclear Cells (PBMCs)
[0127] Blood samples were collected from 3 pancreatic cancer patients, 3 pancreatitis patients, 3 normal control group subjects, 3 lung cancer patients and 3 colorectal cancer patients and stored at room temperature. Since the separation of mononuclear cells is difficult when blood viscosity is high, blood samples were prepared through 1:1 dilution in 1PBS. Ficoll (Histopaque 1077, Sigma) was prepared in the same volume as blood in a 15 ml conical tube. Blood samples were added onto Ficoll such that the blood samples were not mixed. The resulting blood samples were centrifuged at 400 g for 30 minutes with minimum acceleration and deceleration. During this process, a white-cell (mononuclear cell) layer was separately collected, and PBS was added thereto to conduct washing with centrifugation at 400 g for 3 minutes. The washed cells were collected, resuspended in 50 l FACS buffer, and then cultured on ice for 1 hour with a PE anti-mouse IL-10R antibody and a PerCP mouse IL-22R antibody. The cells were then washed twice with FACS buffer and resuspended in 500 l FACS buffer.
[0128] 2. Treatment with Brefeldin A
[0129] The collected cells were counted, seeded at 110.sup.6 cells/ml in RPMI 1640 medium containing 2% penicillin and streptomycin, treated with 1Brefeldin A and cultured for 6 hours.
[0130] 3. Fixing, Perming and Staining
[0131] The cultured cells were collected, washed twice with FACS buffer (0.5% BSA in PBS), and fixed with 500 l of fixed buffer on ice for 30 minutes. Then, the cells were washed twice with FACS buffer, resuspended in 1 ml of perm buffer and then centrifuged twice for 20 minutes. Then, the cells were collected again, resuspended in 50 l of perm buffer and then cultured on ice for 1 hour with Alexa 647 anti-IL-22 antibody. The cells were washed twice with FACS and resuspended in 500 l of FACS buffer.
[0132] 4. FACS Analysis
[0133] The number of cells expressing IL-10R, IL-22R or IL-22 relative to the total number of mononuclear cells was expressed in % using a FACSCalibur (BD Biosciences, San Jose, Calif.). The results are shown in the following Table 1 and
TABLE-US-00001 TABLE 1 Mean SD (%) Normal Pancreatic Lung Item control group Pancreatitis cancer cancer Colorectal cancer IL-22 2.44 0.02 4.06 3.49 2.25 1.31 0.51 0.43 0.21 0.01 IL-22R 2.16 0.49 40.30 8.00 14.20 14.88 0.60 0.55 0.37 0.13 IL-10R 2.59 0.75 38.40 7.80 23.20 8.65 7.13 4.93 2.01 0.89
[0134] As shown in Table 1 and
[0135] In addition, it was found that, regarding the expression level of IL-22R, the pancreatitis patients had an increase of about 18.66 times compared to the normal control group, and the pancreatic cancer patients had an increase of about 6.57 times compared to the normal control group. However, the lung cancer patients had a decrease of about 0.28 times compared to the normal control group and the colorectal cancer patients had a notable decrease of about 0.17 times compared to the normal control group.
[0136] Further, regarding the expression level of IL-22R relative to IL-22, the expression level of IL-22R relative to the expression level of IL-22 in pancreatitis patients was about 9.93 times, and the expression level of IL-22R relative to the expression level of IL-22 in pancreatic cancer was about 6.31 times. This indicates that, although IL-22 binds to IL-22R, the expression level of IL-22R was significantly increased compared to IL-22. However, the expression level of IL-22R relative to the expression level of IL-22 in lung cancer patients was about 1.18 times, and the expression level of IL-22R relative to the expression level of IL-22 in colorectal cancer patients was about 1.76 times. This indicates that the expression level of IL-22 is similar to that of IL-22R.
[0137] These results demonstrate that the expression level of IL-10R in pancreatitis or pancreatic cancer patients is clearly differentiated from that of the normal control group or patients of other diseases, and pancreatitis and pancreatic cancer also have distinct expression behaviors.
[0138] Therefore, with the method according to the present invention, pancreatitis and pancreatic cancer can be detected and diagnosed with high accuracy, and the diagnosis can be carried out while distinguishing between pancreatitis and pancreatic cancer.

[0146] As shown in
[0147] These results indicate that the mRNA expression level of interferon receptor 1 isoform 1 detected in PBMCs was significantly increased in pancreatic cancer compared to other types of cancer.

The results are shown in the following Table 2 and
