Inhibitory1
- It is one of several ways to block inhibitory signals related to T-cell activation, a more general strategy known as "immune checkpoint inhibition. (thermofisher.com)
Cells13
- Called antibody-dependent enhancement (ADE), this happens when the antibodies stick to the outside of the virus without blocking its ability to infect cells, which can inadvertently help the virus infect more cells by allowing it to enter cells that the antibodies stick to. (news-medical.net)
- And then use the expertise that we have to target specific cells of the airway to transform the cells of our nose into almost mini factories that could actually produce antibody. (thenakedscientists.com)
- This then goes into the nose, into the airways, and the cells that take up that virus get the gene for the antibody so they start making and secreting the antibody. (thenakedscientists.com)

- It works by blocking certain blood cells from interacting. (medlineplus.gov)
- A purple well means the antibodies in the serum sample prevented poliovirus from infecting and killing cells within the cell culture. (cdc.gov)
- If the well shows up as colorless, this means that antibodies did not block the virus from infecting and killing the cells. (cdc.gov)
- The presence of antibodies in a serum sample, capable of blocking poliovirus from infecting cells, means that the person, from whom the sample was extracted, is protected from developing paralysis after exposure to poliovirus. (cdc.gov)
- Targeted antibodies that prevent leukaemia stem cells from multiplying while attracting the natural killer cells of the body, which in turn send a death signal to the diseased stem cell. (lu.se)
- The killer cells are drawn to the antibody because it has indicated that something is wrong inside the body and, in turn, the killer cells send out a death signal to the AML stem cell. (lu.se)
Prevents1
- The ingestible or inhalable antibody prevents allergic reactions and asthma in adults, by binding to molecules which would otherwise cause allergy. (medindia.net)

Clinical trials1
- Blockade of CTLA-4 by antibodies has potentiated antitumor T-cell responses in both preclinical models and clinical trials. (aacrjournals.org)
Search1
- What makes this antibody different is that its search did not take place in people who had COVID-19, but in someone infected 17 years ago during a SARS epidemic. (globalbiodefense.com)
Vaccine6
- The blocking of MSP-1 has been proposed to be a method of creating a vaccine against malaria by preventing its invasion and multiplication. (wikipedia.org)
- Targeted rational vaccine strategies could take advantage of this molecular information of the interactions of these antibodies with the S2 domain to inform the design of pan-betacoronavirus vaccines," Wilson said. (indiatimes.com)

Abstract1
- Abstract Monoclonal antibodies blocking immune checkpoints such as PD-L1 have yielded strong clinical benefits in many cancer types. (ox.ac.uk)
Conclusions2
Therapies2
- These viruses mutate at a modestly high rate, creating a significant challenge for the development of vaccines and antibody therapies against them. (indiatimes.com)
- However, these therapies may be helpful in early first- and second-degree heart block and in reducing associated myocardial dysfunction. (medscape.com)
Molecules1
- These findings are taken to be strong evidence in favor of qualitatively demonstrable separate antibody molecules dealing with two separate functions, i.e., cytotoxicity versus enhancement or immunoregulation. (northwestern.edu)
Demonstrable1
- [ 14 ] When MMN is defined clinically, some patients may not have demonstrable conduction block on conventional NCS. (medscape.com)
Widely2
- So when people see advertisements for finger-prick antibody tests becoming widely available at places like urgent care centers and medispas, they should think twice, experts warned. (latimes.com)
- Specific anti-TGF- obstructing antibodies or Inolitazone dihydrochloride Galunisertib were widely used in these studies, being useful tools to demonstrate that NKG2D down-regulation is mainly mediated by this cytokine [30,32,37,39,46,47]. (abic2004.org)
Dilution1
- Please refer to primary antibody product webpage for recommended antibody dilution. (cellsignal.com)
Secondary3
- The binding of blocking antibodies to MSP-1 is shown to result in the inhibition of secondary processing, resulting in the inability for merozoites to invade host erythrocytes. (wikipedia.org)
- The next day, the membranes are washed at room temperature with agitation three times for 10 minutes in 5 % non-fat milk in TBST and incubated with a secondary antibody for two hours at room temperature with gentle rocking. (cdc.gov)
- Major criteria for pacing based on ECG or Holter monitoring include an average heart rate of less than 50 bpm, a nighttime or sleeping average heart rate of less than 45 bpm, or pauses secondary to AV block that are longer than 3 seconds. (medscape.com)
Specific1
- During the first incubation step, anti-HEV specific antibodies, if present, will be bound to the solid phase pre-coated HEV antigens. (cdc.gov)
Viruses2
- But those antibodies didn't work against all of the viruses that cause arthritis and failed entirely against the ones that cause brain infections. (innovitaresearch.com)
- Both antibodies protected the animals against all of the viruses. (innovitaresearch.com)
Coronaviruses1
- That is probably why this antibody, instead of being single-minded, can act against related coronaviruses. (globalbiodefense.com)
