T 세포의 레지 단지 소수 쥐와 인간에서 존재하지만, 그들은 면역 반응을 조절하고 면역 관용을 유지하는데 중요한 역할을 그들의 기능을 이해하는 것이 중요하다. T의 수와 억제 기능은 만성 바이러스 감염 15-20뿐만 아니라 암의 진행 도중 13,14 세포 증가 REG. 이것은 아마도 계속 항원 자극에 기인한다. 레지 세포 항원 지속성 및 질병 개발 함수 T를 평가하?...

규제 T (T의 REG) 세포는 개발 및 기능 1 전사 인자로 forkhead 상자 P3 (Foxp3의)을 표현한다. 또한, T의 등록 세포는 CD25이 림프구 활성화 유전자 3 (LAG-3) (3), 글루코 코르티코이드 - 유도 된 종양 괴사 인자 수용체 (4) 및 세포 독성과 같은 다양한 분자를 발현 T 림프구 회합 단백질 4 (CTLA-4) (5) 그 표면 또는 세포 내 영역에. 바이러스 6,7, 8,9 박테리아, 기생충 10-12 또는 암 13,14 개발 과정에서 병원체 각종 만성 감염 동안 T에 등록 셀은 향상된 억제 기능을 표시 활성화 세포로 분화 될 대상 이펙터 CD4 +와 CD8 + T 세포. 많은 논문 확장 활성화 T에 등록 세포가 손상된 CD8 + T 세포 응 답에 기여한다고 제안했다친구 레트로 바이러스 (FV) 감염 15 ~ 17시 전자. FV 유발 T에 등록 셀은 IFN-γ 또는 그랜 자임 B 발현 및 CD8 + T 세포의 세포 독성 15-17 반응성을 억제한다. 또한, 단순 포진 바이러스 감염 모델에서, 이는 바이러스 - 특이적인 CD8 + T 세포 및 immunopathogenic CD4 + T 세포를 18-20의 침윤 심각한 조직 손상의 확대 결과 CD4 + CD25 + T에 등록 세포의 고갈을보고 하였다. 림프 구성 맥락 수막염 바이러스의 복제 13 균주 만성적으로 감염된 마우스 (LCMV CL13) 21-24 널리 만성 바이러스 감염 동안 효과기 T 세포 (T의 EFF) 및 T의 등록 세포의 표현형 및 기능을 특성화하는데 사용되어왔다. 영구 LCMV 감염시 바이러스 관련 T EFF의 세포는 점차적으로 자신의 이펙터 기능을 잃고 지쳐 T (T의 배기) 세포가된다. 한편, T에서레지 세포는 바이러스 특이 적 T 세포 반응 (25)을 억제하는 능력을 강화한다. T 개의 EFF 셀의 작동 능력의 감소는 이러한 T EFF 세포 억제 성 수용체의 상향 조절, 항원 제시 세포의 변경 기능, 면역 조절 사이토 카인의 생산 및 증가 된 주파수 또는 T의 등록 향상된 기능 등 여러 가지 요인들에 의해 설명 될 수있다 세포 26. T 세포 억제에 관여하는 요소 중에서, 프로그램 된 세포 사멸 단백질 -1 (PD-1) 발현 T의 배기 세포와 T에 등록 세포 널리 항원 지속성 및 억제 환경의 특징으로 간주되어왔다. 최근에는 T의 등록 셀의 PD-1 경로의 폐색 및 제거를 향상 T 세포의 기능을 야기한다는보고 LCMV 만성 감염시 바이러스로드 (27)가 감소 하였다. 또한, T의 등록 세포는 LCMV (23, 25)와 쥐의 만성 감염시 활성화 </s업&gt;과 억제 기능 (25)을 강화한다. PD-1은 높은 T에 등록 세포뿐 아니라 T의 배기 세포 발현되며, PD-1 T에 등록 세포에 의해 발현 수준은 T 세포의 증식 (25)을 억제하는 그들의 억제 기능의 강도와 상관 관계. 여기서는 LCMV CL13 및 나이브 마우스로부터 단리 휴지 T에 등록 세포 감염 쥐로부터 분리 활성화 T 등록 세포의 특성을 비교하는 방법을 설명한다. 더욱이, 우리는 활성화 된 T 세포의 레지 분리 및 표현형 생체 검사뿐만 아니라 시험 관내에서의 억제 활성을 측정하기위한 일련의 처리를 설명한다.

Phenotypic and Functional Analysis of Activated Regulatory T Cells Isolated from Chronic Lymphocytic Choriomeningitis Virus-infected Mice

Here, we describe a protocol to analyze the phenotype of regulatory T (Treg) cells isolated from na&#239;ve and chronic lymphocytic choriomeningitis virus-infected mice. In addition, we provide a process to evaluate the suppressive activity of the Treg cells.

The overall goal of this procedure is to evaluate the in vitro suppressive function of regulatory T cells, isolated from chronic virus infected mice. This method can help answer questions about the phenotype and in vitro suppressive function of activated regulatory T cells during a chronic virus infection. This technique can evaluate the direct effect of regulatory T cells on the individual with a positive response to T cells in vitro.This is a great advantage of this technique. Begin by transferring five times ten to the fifth total splenic lymphocytes in 50 microliters of facs buffer into each well of a new U bottom 96 well plate, followed by 150 microliters of facs buffer. Centrifuge the plate and discard the supernatant.Then agitate the cell pellets and wash the cells two more times in 200 microliters of facs buffer per well. After the second wash, resuspend the pellets in 50 microliters of antibody cocktail per well, for 20 minutes in the dark at four degrees Celsius. Then wash the cells two times in facs buffer, and decant the supernatant.Next, fix the cells for 20 minutes in the dark at four degrees Celsius with 100 microliters of fixation buffer, followed by two washes with permeabilization wash buffer. After the second wash, resuspend the cells in 50 microliters of anti-FOXP3 antibody. To prepare the anti CD3 CD28 coated beads, transfer the appropriate volume of magnetic beads into a 15 milliliter tube, and add an equal volume of PPS.Gently mix the solution by pipetting, and centrifuge the magnetic beads. At the end of the wash, discard the supernatant, and dilute the beads in 50 microliters of complete medium per well. Next, seed 50 microliters of one times ten to the fifth CD4 positive CD25 positive regulatory T cells per well in a 96 well U bottom plate, followed by 50 microliters of one times ten to the fifth CD8 positive responder T cells per well.When all of the cells have been plated, add 50 microliters of the diluted anti CD3 CD28 coated beads to each well, and add up to 50 microliters of medium to bring the total volume of each well up to 200 microliters. Then cover the plate with foil and place it at 37 degrees Celsius in a carbon dioxide incubator for 72 hours. To analyze the CD8 positive T cell cytokine production, after three days of culture, transfer the supernatants into another 96 well plate and analyze the supernatants by ELISA, according to the manufacturer's instructions.To analyze the proliferation of the CD8 positive T cells, wash the plate of cells with facs buffer three times. Then resuspend the pellets in 50 microliters of an appropriate antibody cocktail against proliferated CD8 positive T cells for 20 minutes in the dark at four degrees Celsius. At the end of the incubation, wash the cells two times in facs buffer and fix them for 20 minutes in the dark at four degrees Celsius with 100 microliters of fixation buffer.Finally, wash the cells two more times in facs buffer and resuspend the pellets in 200 microliters of facs buffer. Then measure the percentage of phylate dilabelled CD8 positive T cell proliferation by flow cytometry. In splenic lymphocytes obtained from naive and infected mice, PD-1 is specifically up regulated in both conventional FOXP3 negative CD4 positive and FOXP3 negative CD8 positive cells of LCMV clone 13 infected mice.The frequency of FOXP3 positive CD4 positive regulatory T cells is two times higher in LCMV clone 13 infected mice than in naive mice, with most of the FOXP3 positive CD4 positive cells also displaying an activated PD-1 high phenotype. CD8 positive responder T cells can be separated successfully without significant contamination by other immune cells. After regulatory T cell isolation, a dominant population of CD25 positive CD4 positive T cells with more than 80 percent purity can be obtained.The stimulation of isolated regulatory and responder T cells by anti CD3 CD28 coated beads results in the inhibition of CD8 positive responder T cells in a dose dependent manner. Indeed, when CD8 positive responder T cells are co-cultured with chronic regulatory T cells at a one to one ratio, the CD8 positive responder T cell proliferation is significantly inhibited. Interferon gamma production by CD8 positive responder cells is also significantly inhibited when CD8 positive responder T cells are co-cultured with activated regulatory T cells from chronically infected mice, compared to co-culture with resting regulatory T cells from naive mice.We have found this technique can be completed in 80 hours if it is performed properly. While you are attempting this procedure, it is important to remember to use freshly isolated regulatory T cells immediately after their isolation. After this development, this technique paved the way for researchers in the field of medicine to explore the function of regulatory T cells in a chronic inflammatory disease.After watching this video, you should have a good understanding of how to set up an in vitro regulatory T cell suppression procedure, using a regulatory and responder T cell co-culture system.
