This technology is a device and system for expediting the thawing frozen specimens (e.g., cryopreserved cells) contained in cryo-vials, offering a breakthrough solution for researchers seeking efficiency and precision in their workflows. The device is equipped with a small elongated tubular adaptor that suspends a cryo-vial of frozen cells over a centrifuge tube containing culture medium in an inverted position. With a focus on speed, efficiency and automation, the adaptor dramatically expedites the process of recovering viable cells from frozen specimens.

Spatial proteomics and transcriptomics are fast-emerging fields with the potential to revolutionize various branches of biology. In the last five years, various multiplex immunofluorescence and immunohistochemistry imaging methods have been developed to stain 5-60 different protein markers in a given tissue. Nonetheless, most of these techniques are iterative and can image a maximum of 3-8 markers in a single cycle, resulting in processing time of several hours to days.

Researchers at the Vaccine Research Center (“VRC”) of the National Institute of Allergy and Infectious Diseases (“NAID”) continue to pursue a safe and effective HIV-1 vaccine to combat the HIV-1/AIDS pandemic.

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).

Scientists at NIAID have developed two immortalized stable B cell lines from rhesus macaques that can have value as research tools for the discovery of neutralizing antibodies of simian origin against HIV and that may have value in the development of an HIV vaccine. These B cell lines encode human Bcl-6 and Bcl-xL proteins, which are major regulators of apoptosis. These B cell lines are derived from the lymph node of a rhesus macaque (RM) that was infected with SHIV.CH505.

Despite four decades of intensive research, a safe and effective HIV-1 vaccine remains elusive due to the extreme difficulty in eliciting broadly neutralizing antibodies (bNAbs), which recognize and block HIV-1 from entering healthy cells. Only rare natural HIV-1 envelopes (Envs) promote the activation and expansion of naive B cells expressing unmutated germline antibodies of various bNAb lineages, but they typically do so for a single lineage for the same neutralization site.

The emergence of the SARS-CoV-2 virus and its immune-escaping variants have led to global COVID-19 pandemic/endemic, underscoring the urgent need for effective vaccines with strong and durable immune responses.

This technology includes an IgA antibody, specifically designed to target the receptor binding domain of SARS-CoV-2, the virus causing COVID-19. Administered intranasally, this antibody has potential neutralizing activity, aiming to prevent COVID-19. IgA, an antibody class present in mucosal areas, plays a crucial role in immune defense at the initial site of viral infection. The primary application of this technology is envisioned as a therapeutic nasal spray, intended to prevent SARS-CoV-2 infection, particularly in high-risk populations.

This technology includes a straightforward and versatile nanotechnology-based approach for in situ therapeutic vaccination that exploits a primary tumor as a vaccine depot to initiate robust personalized anti-tumor immune responses.

In 2022, the World Health Organization declared an atypical outbreak of monkeypox (Mpox), which has caused approximately 30,000 cases of Mpox infection within the United States as of April 2023. Mpox represents a current threat to public health, and there is an immediate need for an effective vaccine. To address this, NIAID has developed a vaccine approach comprising virus-like nanoparticles coated with modified Mpox proteins.
