CRM197-scaffolded vaccines designed by epitope grafting ameliorate cognitive decline in an Alzheimer's disease model

Article

Alzheimer's disease (AD) is the leading cause of dementia in the elderly. Amyloid-beta (Aβ) plaque accumulation and tau neurofibrillary tangles (NFTs) formation in the brain are major neuropathological hallmarks of AD. Immunotherapies targeting Aβ and/or tau are deemed the most promising approaches for AD. Administrations with monoclonal antibodies against Aβ have yielded substantial breakthroughs clinically. Most vaccines tested clinically so far failed to prove efficacious in large part due to inappropriate design of vaccine antigens. In this study, a structure-guided approach was employed to design novel antigens targeting Aβ and/or tau by grafting multiple copies of Aβ and/or tau B-cell epitope peptide onto CRM₁₉₇, which is the most widely used carrier protein in polysaccharide conjugate vaccines. The immunogenicity of the vaccines was evaluated in BALB/c mice and the efficacy was tested in a transgenic mouse model of human amyloidopathy. The antigens were highly immunogenic early vaccination substantially ameliorated cognitive decline in APP/PS1 mice and significantly reduced insoluble Aβ_42/40 in the brains. These results demonstrate that the engineered antigens have protective effects on AD mice, offering a promising translatable strategy for the prevention and/or treatment of AD.

Convergent Synthesis of a Group B Streptococcus Type III Epitope Toward a Semisynthetic Carbohydrate-Based Vaccine

Article

Author: Archambault, Marie-Jeanne ; Giguère, Denis ; Bahadori, Sam ; Sebastiao, Mathew ; Bourgault, Steve

In this work, we synthesized an hexasaccharide derived from the capsular polysaccharide of group B Streptococcus type III capsular polysaccharide. Our convergent 3 + 3 strategy avoided the use of benzyl protecting groups allowing the installation of an azide anchoring group and providing a high yield for the final deprotection steps. Moreover, the minimal hexasaccharidic epitope was conjugated to CRM₁₉₇ and BSA via copper-catalyzed azide-alkyne cycloaddition for the preparation of a semisynthetic carbohydrate-based vaccine.

Immunotherapeutic approaches for Alzheimer’s disease: Exploring active and passive vaccine progress

Review

Author: Belemkar, Sateesh ; Roul, Krishnashish ; Kumar, Devendra ; Bhadane, Priyanshu

Alzheimer's disease (AD) is the most common neurodegeneration having non-effective treatments. Vaccines or monoclonal antibodies are two typical immunotherapies for AD. Due to Aβ neurotoxicity, most of the treatments target its generation and deposition. However, therapies that specifically target tau protein are also being investigated. UB311 vaccine generates N-terminal anti-Aβ antibodies, that neutralize Aβ toxicity and promote plaque clearance. It is designed to elicit specific B-cell and wide T-cell responses. ACC001 or PF05236806 vaccine has the same Aβ fragment and QS21 as an adjuvant. CAD106 stimulates response against Aβ_1-6. However, Nasopharyngitis and injection site erythema are its side effects. AN1792, the first-generation vaccine was formulated in proinflammatory QS21 adjuvant. However, T-cell epitopes are omitted from the developed epitope AD vaccine with Aβ_1-42B-cell epitopes. The first-generation vaccine immune response was immensely successful in clearing Aβ, but it was also sufficient to provoke meningoencephalitis. Immunotherapies have been at the forefront of these initiatives in recent years. The review covers the recent updates on active and passive immunotherapy for AD.

Developing a vaccine for the 'zombie drug' xylazine

Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people. Xylazine is an FDA-approved sedative and pain reliever for use in animals, but it has severe adverse effects when used in humans. It is now illicitly being added to opioids, like fentanyl and heroin, as well as cocaine -- leading to a sharp rise in overdose deaths. Now, Scripps Research chemical biologists have developed a vaccine to block the effects of xylazine's toxicity. The vaccine works by training the immune system to attack the drug, which is described in a new paper published in Chemical Communications on April 1, 2024. "We demonstrated that a vaccine can reverse the symptoms of a xylazine overdose in rodents," says study senior author Kim D. Janda, PhD, the Ely R. Callaway, Jr. Professor of Chemistry at Scripps Research. "There is currently no remedy for xylazine poisoning other than supportive care, thus, we believe our research efforts and the data we have provided will pave the way for an effective treatment in humans." The rapid increase in lethal drug overdoses attributed to xylazine combined with fentanyl prompted the White House Office of National Drug Control Policy to declare this combination an emerging threat to the United States. Xylazine intoxication presents similarly to opioid overdose, causing respiratory and central nervous system depression, and it can heighten the effects of opioids. However, naloxone -- typically administered to reverse the effects of opioids -- does not tackle the impact of xylazine, highlighting the need for effective measures to treat acute toxicity caused by xylazine. Researchers suspect xylazine works by reducing blood flow to the brain, among other areas of the body. The drug also causes non-healing skin lesions and wounds, often located on the forearms and lower legs, that can require amputation in some cases -- giving it the nickname "zombie drug." Although no treatment currently exists, targeted vaccines may offer a solution. Vaccines nudge the immune system to create antibodies to fend off invaders. Antibodies can target viruses, bacteria and toxins. However, sometimes molecules are too small to initiate an immune response, as is the case with xylazine. So, to circumvent this problem, the researchers created a vaccine using a design principle that Janda pioneered, which relies on pairing the drug molecule (called a hapten) with a larger carrier molecule (a protein) and an adjuvant. In this study, the scientists combined a xylazine hapten with multiple different protein types, to see which combination would create a robust immune response against xylazine. The team tested three vaccine formulations (termed TT, KLH and CRM197, based on the protein involved) to see which vaccine cocktail could help rodents after being challenged with xylazine. One of the three vaccines (TT) significantly increased movement in mice given xylazine after 10 minutes, while two of the three vaccines (TT and KLH) led to an improvement in breathing. The scientists also examined how these vaccines would limit xylazine blood brain barrier, (BBB) permeation, a filtering mechanism that scrutinizes drug penetration. When xylazine was injected, it immediately crossed into the brain to bind with receptors. Antibodies typically cannot navigate the BBB; however, two of the three vaccines (TT and KLH) showed a strong ability to stop xylazine from reaching its receptors in the brain, limiting its detrimental effects. A provisional patent has been filed on the research. In the future, his team will build off this work to create a bifunctional antibody that will reverse both fentanyl and xylazine's toxicity simultaneously, something that naloxone cannot do. "A monoclonal antibody treatment could be given in tandem with the vaccine to provide both immediate and long-term protection from both opioid substance use disorders as well as opioid-xylazine overdoses," says Janda. "This strategy could make a significant impact on the opioid epidemic." "Evaluation of a Hapten Conjugate Vaccine Against the 'Zombie Drug' Xylazine" was co-authored by Mingliang Lin, Lisa M. Eubanks, Bin Zhou, and Kim D. Janda, all of Scripps Research. Funding for the study was provided by the Shadek family and Pearson Foundation.
