Biofilms are complex microbial communities, surface attached and held together by self-produced polymer matrices. These matrices are mainly composed of polysaccharides, secreted proteins and nucleic acids. Poly-N-acetyl glucosamine (PNAG) is a highly conserved surface polysaccharide expressed by a range of bacterial, fungal and protozoan microorganisms.
The Zbtb7b gene encodes the zinc finger transcription factor ThPOK (also known as cKrox) that promotes CD4 lineage differentiation in immature T cells. CD4+ T cells, also known as “helper” T cells, are critical for long-term immunity against pathogens as well as for promoting CD8+ “effector” T cell and effective B cell responses. ThPOK is needed for the development and functional fitness of CD4+ T cells as well as multiple aspects of the immune response to infection. As such, ThPOK offers a potential target for immune regulation.
Human immunodeficiency virus (HIV) remains a major global health challenge despite the advancement made in development of effective antiretrovirals (ARVs). ARVs are effective at limiting replication and spread of the virus, and progression to acquired immuno-deficiency syndrome (AIDS). However, ARVs often lead to emergence of drug-resistant virus strains insensitive to treatment and with toxic effects following long-term usage.
Adoptive cell therapy (ACT) is a breakthrough form of cancer immunotherapy that utilizes tumor infiltrating lymphocytes (TILs) or genetically engineered T cells to attack tumor cells through recognition of tumor-specific antigens. A major hurdle in the development of ACT is the identification and isolation of T cells that recognize antigens that are expressed by tumor cells but not by healthy tissues. Current methods to identify such T cells involve extracting autologous antigen presenting cells (APCs) from patients in an expensive, laborious, and time-consuming process.
Computer and imaging technologies led to the development of digital pathology and the capture and storage of pathological specimens as digitally formatted images. The use of artificial intelligence (AI) in digital pathology, such as in three-dimensional (3D) reconstruction, requires analyses of high volumes of data. This results in increased demands for processing and acquisition of digital images of pathology samples. Increased usage cannot be met by the time-consuming, manual, and laborious methods currently used.
Vaccines have become one of the most important tools in the fight against cancers and infectious diseases. However, some vaccines have shown limitations due to their high cost and low immune responses. To overcome these limitations, bacteriophages were proposed for the development of more cost-effective, immunogenic vaccines. Phages have shown a strong ability to activate induced and adaptive immune systems. The genome of these viral particles can be engineered, and their surface proteins can be exploited for antigen display.
Human papillomavirus (HPV) is a group of human viruses known to cause various malignancies. Of the group, HPV-16 is the most prevalent strain – an estimated 90% of adults have been exposed. HPV-16 is also the strain most commonly associated with malignancy, causing the vast majority of cervical, anal, vaginal, vulvar, and penile cancers. Currently, HPV-positive malignancies non-responsive to surgery or radiation are incurable and poorly palliated by existing systemic therapies. Thus, an alternative therapeutic approach for HPV-positive malignancies is needed.

The COVID-19 pandemic is a worldwide public health crisis with over 440 million confirmed cases and 6.0 million deaths as of March 2022. COVID-19 is caused by a novel coronavirus called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). While there are several vaccines available for COVID-19, there are few therapeutics available that specifically target SARS-CoV-2. Middle East respiratory syndrome coronavirus (MERS-CoV) is less understood than SARS-CoV-2. MERS-CoV patients have a 65% long-term survival rate, according the World Health Organization (WHO).
Immunotherapy is a cutting-edge new category of treatment that aims to harness and, in some cases, modify the patient’s own immune cells to improve their ability to cure diseases. It can be an effective approach for a variety of conditions, ranging from cancer to inflammatory diseases. However, a number of obstacles to the overall success of immunotherapy still exist. For example, reactivity against a target antigen can be attenuated or the lifespan of the “modified” immune cells can be too short.
