Over the past decade, the safety and efficacy of the anti-CD20 antibody rituximab has resulted in its use in virtually all patients with B-cell non-Hodgkin's lymphoma (NHL). Unfortunately, many patients who initially benefit from rituximab develop resistance while others may never respond. Both the successes and limitations of rituximab have heralded an explosion in research and development of novel monoclonal antibodies. Strategies employed to improve upon rituximab have included developing antibodies to target new epitopes of CD20 and new antigens, humanizing or creating fully human antibodies, and engineering antibodies with a potentially greater capacity for interaction with the host immune system. Each of these strategies has shown varying degrees of preclinical and clinical success. In this review we discuss the rationale for various strategies and report results from clinical trials employing these agents.

The biological characteristics of early transmitted/founder (T/F) variants are crucial factors for viral transmission and constitute key determinants for the development of better therapeutics and vaccine strategies. The present study aimed to generate T/F viruses and to characterize their biological properties. For this purpose, we constructed 18 full-length infectious molecular clones (IMCs) of HIV from recently infected infants.

SARS-CoV-2 infection induces a humoral immune response, producing virus-specific antibodies such as IgM, IgG, and IgA. IgA antibodies are present at mucosal sites, protecting against respiratory and other mucosal infections, including SARS-CoV-2, by neutralizing viruses or impeding attachment to epithelial cells. Since SARS-CoV-2 spreads through the nasopharynx, the specific IgAs of SARS-CoV-2 are produced quickly after infection, effectively contributing to virus neutralization.

Plague, caused by , poses a public health threat not only due to sporadic outbreaks across the globe but also due to its potential as a biothreat agent. Ironically, among the seven deadliest pandemics in global history, three were caused by . Pneumonic plague, the more contagious and severe form of the disease, is difficult to contain, requiring either prophylactic antibiotic treatment or vaccination.

Respiratory syncytial virus (RSV) is a leading cause of respiratory infections, particularly affecting young infants, older adults, and individuals with comorbidities. : This document, developed as a consensus by an international group of experts affiliated with the World Association of Infectious Diseases and Immunological Disorders (WAidid), focuses on recent advancements in RSV prevention, highlighting the introduction of monoclonal antibodies (mAbs) and vaccines. : Historically, RSV treatment options were limited to supportive care and the monoclonal antibody palivizumab, which required multiple doses.

The discovery of immune checkpoints (ICs) has pushed cancer treatment into the next era. As an emerging immune checkpoint, the TIGIT/CD155 axis inhibits the cytotoxicity of T and NK cells through multiple pathways. Immune checkpoint inhibitors (ICIs) targeting TIGIT are hopefully expected to address the issue of unresponsiveness to anti-PD-(L)1 monoclonal antibodies (mAbs) by combination therapy.
