Antigen-specific monoclonal antibodies are useful tools to detect very small amounts of antigenic materials and are applicable for antibody therapeutics. To produce mouse monoclonal antibodies, a hybridoma between B lymphocytes and myeloma cells is used to produce antigen-specific monoclonal antibodies. However, a good hybridoma system is not available to obtain human monoclonal antibodies. To produce antigen-specific human monoclonal antibodies, transformation of B lymphocytes with Epstein-Barr viruses or a phage-display system is used. Here, we describe the screening of antigen-specific, antibody-secreting cells using microwell array chips to obtain antigen-specific human monoclonal antibodies. The system can be applied to screen antigen-specific, antibody-secreting cells from any animal species.

Influenza virus neuraminidase (NA) is a crucial target for protective antibodies, yet the development of recombinant NA protein as a vaccine has been held back by instability and variable expression. We have taken a pragmatic approach to improving expression and stability of NA by grafting antigenic surface loops from low-expressing NA proteins onto the scaffold of high-expressing counterparts. The resulting hybrid proteins retained the antigenic properties of the loop donor while benefiting from the high-yield expression, stability, and tetrameric structure of the loop recipient.

Managing moderate-to-severe psoriasis in patients with current or past malignancy remains a therapeutic challenge. We conducted a multicentre, retrospective real-world study to assess the safety and effectiveness of guselkumab in this complex population. Thirty patients were included, of whom 11 had active cancer at the time of guselkumab initiation.

Background: Fel d 1, the primary allergen produced by cats, is a glycoprotein found mainly in their salivary and sebaceous glands. Due to its small size and stability, it easily becomes airborne and adheres to surfaces, posing a persistent problem for allergic individuals.
Methods: This article reviews innovative strategies aimed at reducing Fel d 1 expression and exposure and mitigating its allergic effects on humans.

Treatment of glioblastoma multiforme (GBM) has been a great challenge before medical fraternity since last century owing to a median survival of less than 15 months, despite of intensive therapy. Neurosurgeries, intense chemotherapy, advanced radiotherapy, and targeted therapies have bought some extension to the life of GBM patients. Combination and targeted therapies could bring a concrete approach to tackle the complexities of GBM treatment.

One of the major reason of deaths due to cancer globally is caused by lung cancer of which the two main types include non-small cell and small cell lung cancer. The onset of treatment-resistance in cancer cells offers a serious obstacle to the therapeutic effect despite that primary conventional treatments have provided significant benefits and cures. Cancer immunotherapy offers a compelling alternative in patients by utilizing their immune system to enhance its ability to fight against tumors.
