CAR-iNKT Cells Targeting Clonal TCRVβ Chains as a Precise Strategy to Treat T Cell Lymphoma

2023-11-09T13:27:52-05:00June 16th, 2023|Case Studies|

With 22 functional T cell receptor (TCR)Vβ subunit families making up the normal T cell repertoire, signals from these cell surface receptors often determine the fate of normal cells. However, mutations in TCR signaling proteins are frequently associated with peripheral T cell lymphomas (TCLs), including adult T cell leukemia/lymphoma (ATL), which indicates a driving role for TCRs in TCL oncogenesis. As TCL and ATL are clonal in nature, tumour cells typically express a single TCRVβ subunit with no bias in the usage of TCRVβ subunit families. Consequently, targeting the specific TCRVβ subunit presents a promising therapeutic approach that is highly selective and tumour-specific.

The great debate on the use of in vivo versus in vitro sources and strategies for antibody discovery and generation continues to thrive among antibody research groups. On one side of the debate is the argument for non-animal-derived antibodies due to the technical advancements of current in vitro technologies, and the moral obligation to reduce animal usage. On the other side of the debate is the counterargument for animal-derived antibodies due to their better performance in affinity, specificity, and reduced immunogenicity risk.

Characterization and Modulation of Anti-αβTCR Antibodies and Their Respective Binding Sites at the βTCR Chain to Enrich Engineered T Cells

2023-06-21T11:00:56-04:00June 17th, 2022|Case Studies|

αβTCR-engineered T cells have been applied in clinical trials, specifically directed against cancer/testis antigens. Though the clinical outcomes are promising, only a small proportion of patients benefit from these novel treatments. Lower response rates are partially attributed to a heterogeneous mixture of non-engineered and poorly engineered T cells that remain in the administered therapeutic product. For successful translation of these novel treatments into the clinic, engineering efforts should be reinforced with effective methods for engineered T cell purification and engineered T cell elimination post infusion into patients.

Broadly Neutralizing Antibody Cocktails Targeting Nipah Virus and Hendra Virus Fusion Glycoproteins

2023-06-21T10:18:26-04:00April 29th, 2022|Case Studies|

Hendra virus (HeV) and Nipah virus (NiV) are types of Henipaviruses (HNVs) that originated in bats and can infect the human respiratory system with detrimental consequences. As enveloped, single-stranded RNA viruses, HeV and NiV use attachment (G) and fusion (F) glycoproteins on the envelope membrane to enter host cells. So far, there are no approved therapeutics or vaccines to combat the viruses in humans.
