Determination of Kb/B22–29-tetramer+ CD8 T-cells in diabetic RIP-B7.1 tg mice.
(C) The numbers of Kb/B22–29-tetramer+ CD8 T-cells were determined during the course of pCI/ppinsΔA12–21-mediated EAD: group 1, health mice (n = 3) with blood glucose levels <200 mg/dl; group 2, early diabetic mice (n = 3) with blood glucose levels between 250-350 mg/dl; group 3, diabetic mice (n = 3) with severe diabetes (i.e., blood glucose levels between 400-550 mg/dl). Pancreata of representative mice out of groups 1 to 3 were analyzed histologically for CD8 T-cell influx (CD8+) or stained with hematoxylin-eosin (H&E).

Image caption:
Ppins/(Kb/A12–21)-mediated recruitment of autoreactive T-cells into the pancreatic target tissue. PD-L1−/− mice were immunized with pCI/ppinsΔA12–21 (A) or with both, pCI/ppins+pCI/ppinsΔA12–21 vectors into the right and the left tibialis anterior muscles, respectively (B). Pancreata of representative healthy (A) and early diabetic mice (B) were analyzed histologically for insulin expression (insulin) and influx of CD8+ T-cells (CD8+), or stained with hematoxylin-eosin (H&E).

Image caption:
Adoptive transfer of CD8+ cells successfully migrate to brain post induction of PIFS.
(A) Schematic illustrating the adoptive transfer of sorted perforin competent CD8+ cells into perforin−/− mice followed by induction of PIFS. C57BL/6 perforin−/− mice were irradiated with 400 rads of irradiation and then intravenously injected with 107 GFP+ CD8+ splenocytes (n = 10) or 107 Ly5.1+ CD8+ splenocytes (n = 10). Mice were intracranially infected with TMEV on the following day. PIFS-inducing VP2121–130 peptide or mock E7 control peptide were intravenously administered on day 7, during the peak of CD8 T cell expansion. MRI analysis was performed on the following day to visualize the extent of CNS vascular permeability and then the CNS was harvested for additional assays. Both negative (Experiment I) and positive (Experiment II) sort experiments yielded high purity of CD8+ T cell transfer. (B) Representative confocal microscopic images illustrating co-localization of Ly5.1 and CD8 protein (Experiment I). CNS-infiltrating Ly5.1+ cells colocalized with CD8+ cells 85.7% of the time as measured by confocal analysis. (C) Confocal microscopy showing of representative brain tissue slice showing successful transfer of GFP+ CD8+ T cells (Experiment II). Purity of transfer was analyzed via flow cytometry, 98.0% ± 0.5% of cells that were CD8 positive and GFP positive.

Unrivaled 
| Rat anti Mouse CD8 alpha antibody, clone 53-6.7 detects mouse CD8a, also known as Lyt-2. CD8α is the alpha chain of the CD8 antigen. CD8 is expressed on T-cells, and exists either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. CD8 functions as a co-receptor with the T-cell receptor and mediates efficient cell to cell interactions within the immune system. The CD8 alpha chain specifically binds to class I MHC molecules. Rat anti Mouse CD8 alpha antibody, clone 53-6.7 has been reported to block antigen presentation via MHC class I and inhibit T cell responses to IL-2. Rat anti Mouse CD8 alpha antibody, clone 53-6.7 has also been used for depletion of CD8a+ cells. |
