- Description
- Description: This 3DS223H monoclonal antibody recognizes human CD223 also known as Lymphocyte Activation Gene 3 (LAG-3). LAG-3 is a 70-kDa surface glycoprotein belonging to the Ig superfamily with homology to CD4. LAG-3 binds to MHC class II with higher affinity than CD4 and is thought to be involved in the negative regulation of T cell activation and homeostatic proliferation. Surface expression of LAG-3 has been reported on activated T cells (including regulatory T cells) and NK cells. CD8+ T cells usually express LAG-3 at significantly higher levels than CD4+ T cells. Coexpression of LAG-3 and CD49b has been proposed to identify human and mouse Type 1 regulatory T cells (Tr1 cells).

- Normal human peripheral blood cells were stimulated for 3 days with Human IL-2 Recombinant Protein (Product # 14-8029-81), Anti-Human CD3, and Anti-Human CD28 Functional Grade Purifieds (Product # 16-0037-81 and Product # 16-0289-81). These cells were then surface stained with Anti-Human CD8a FITC (Product # 11-0087-42) and Mouse IgG1 K Isotype Control Alexa Fluor® 700 (Product # 56-4714-80) (left) or Anti-Human CD223 (LAG-3) Alexa Fluor® 700 (right). Viable cells in the lymphocyte gate, as determined by 7-AAD (Product # 00-6993-50), were used for analysis.

- Figure 3 MAVS genetic variation does not affect T cell exhaustion, activation, and senescence. ( a ) Percentages of PD-1 + , LAG-3 + , CD38 + , HLA-DR + , CD134 + , exhausted (PD-1 + LAG-3 + ), activated (CD38 + HLA-DR + ), and senescent (CD27 - CD28 - ) cells within CD4 + and ( b ) CD8 + T cells of untreated HIV-1-infected individuals with a MAVS minor or MAVS major genotype 2.5-3.5 years p.SC were analyzed using flow cytometry. Each square or dot represents a different study participant (median +- IQR). No significant differences between HIV-1-infected individuals with a MAVS minor or MAVS major genotype were observed.

- Figure 4 MAVS minor genotype is associated with a decreased percentage of naive CD4 + T cells. ( a ) Percentages and ( b ) cell counts of naive (T naive ; CD45RA + CD27 + CCR7 + ), terminally differentiated effector memory (TEMRA; CD45RA + CCR7 - CD27 - ), central memory (CM; CD45RA - CCR7 + CD27 + ), transitional memory (TM; CD45RA - CCR7 - CD27 + ), and effector memory (EM; CD45RA - CCR7 - CD27 - ) cells within CD4 + and CD8 + T cells were analyzed using flow cytometry. ( c ) Percentages of exhausted (PD-1 + LAG-3 + ) and activated (CD38 + HLA-DR + ) CD4 + T cells and ( d ) CD8 + T cells within T naive , TEMRA, CM, TM, and EM populations were analyzed using flow cytometry. Each square or dot represents a different study participant (median +- IQR). All significant differences are indicated: * p < 0.05, unpaired Mann-Whitney test.
