CD19 and CD20 are promising targets for the treatment of B-Cell malignancies.  Unfortunately, some clinical studies have shown that there is a loss of CD19 or CD20 expression in various cases of lymphomas and leukemias, particularly after treatment with an agent that targets CD19 (e.g., anti-CD19 CAR-T). However, studies have shown that expression of one protein is retained when the other is lost. This suggests that a therapeutic with the ability to simultaneously target both CD19 and CD20 could represent a solution to the drawbacks of current therapies. 

Optical traps (optical tweezers) have a focused laser beam able to trap a small bead at its focus, and are used to measure the microrheology of gels and other materials. They have recently been used to characterize properties of living cells, however issues of image spatial resolution and limited depth of interrogation have prevented application of an optical trap to measure microrheological (flow of matter) properties in complex (non-uniform) materials, such as multi-cellular systems or living organisms. 

The COVID-19 pandemic is a worldwide public health crisis with over 100 million confirmed cases and 2.4 million deaths as of February 2021. COVID-19 is caused by a novel coronavirus called SARS-CoV-2. SARS-COV-2 infects hosts via its spike (S) protein. The S protein contains the receptor binding domain (RBD) that binds to the angiotensin converting enzyme 2 (ACE2) receptor on human cells to facilitate viral entry and infection. There are few therapeutics available for COVID-19 patients that directly target SARS-CoV-2.

Neuroblastoma is a rare pediatric cancer with approximately 1,000 new cases arising annually. Current therapies have a less than forty-five percent (45%), three-year survival rate which demonstrate a need for a more effective treatment against this disease. Glypican-2 (GPC2) is a cell surface protein that is preferentially expressed in pediatric cancers including neuroblastoma, which makes GPC2 an attractive candidate for targeted therapy. 
 

The COVID-19 pandemic is a worldwide public health crisis with over 100 million confirmed cases and 2.4 million deaths as of February 2021. COVID-19 is caused by a novel coronavirus called SARS-CoV-2. Almost all the neutralizing antibodies targeting SARS-CoV-2 that are in development recognize the receptor binding domain (RBD) on the spike (S) protein. Blocking the interaction of RBD and the ACE2 receptor on human cells is the first of the two critical steps for neutralization of the virus.

Lassa Hemorrhagic Fever (LHF) is a serious disease caused by infection with Lassa virus (LASV) – highly prevalent in West Africa and spreading globally. LASV is associated with high morbidity and mortality rates, annually infecting 100,000 to 300,000 individuals and causing 5,000 deaths. Developing prophylactics and treatment for LASV is difficult due to challenges in inducing neutralizing antibodies and producing their target, the LASV glycoprotein trimer (GPC).

Mesothelin is a cell surface protein that is highly expressed in aggressive cancers, such as malignant mesothelioma, ovarian cancer and pancreatic cancer, lung cancer, breast cancer, cholangiocarcinoma, bile duct carcinoma and gastric cancer.  Because of this selective expression, mesothelin is an excellent candidate for targeted therapeutics, such as monoclonal antibodies (mAbs) and chimeric molecules.  Current anti-mesothelin therapeutic mAb candidates bind to an epitope in Region I of mesothelin.  Unfortunately, Region I contains the interaction site MUC16/CA125, a mesothe

Bacterial spores can be modified to display molecules of interest, including drugs, immunogenic peptides, antibodies and other functional proteins of interest (such as enzymes).  The resulting engineered bacterial spores can provide many useful functions such as the treatment of infections, use as an adjuvant for the delivery of vaccines, and the enzymatic degradation of environmental pollutants.
