For T cell subset analyses, 100 μL of whole blood was mixed with an optimal dilution of the following monoclonal antibodies: CD3-APC-CY7, CD4-PE, CD8-PerCP-Cy5.5, CD45RA-FITC, CCR7-PE-CF594, CD5-PE-CY7, CD27-APC, CD127-V450, CD25-BV510 (BD Bioscience). After adding all antibodies, the mixture was gently vortexed and incubated for 15 min in the dark at room temperature. Subsequently, 2 mL of 1× FACS lysing solution (BD Bioscience) was added and incubated for 10 min in the dark at room temperature. Finally, cells were washed 3 times with 200 μL washing buffer. Data was collected by a 9-colour Aria I flow cytometer (BD Bioscience) and analyzed with FACSDiva software (version 6.1.3, BD Bioscience). The following T cell subsets were determined (Mahnke et al., 2012; Schatorje et al., 2012)
Tem), and CD8 + transitional memory T cells (CD3 + CD8 + CD4 -CD45RA -CCR7 -CD27 + , CD8 + Ttm). The full-minus-one (FMO) principle was adopted for gating the T cell subsets. Absolute counts of each subgroup were calculated by multiplying the total lymphocyte counts with the percentages of each subset that were determined by flow cytometry.

We have previously demonstrated that these CD4+ CD39+ CD25+ Treg are FOXP3+ CD127neg [24 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
