Under normal conditions our immune system protects us against infections and tumors. The immune system does this by recognizing that the infecting organism or the tumor is foreign to the body and attacking it. Read more about this study

About this study

Official title: CCRC: Serum Auto-Antibodies in Neurological Disease

Under normal conditions our immune system protects us against infections and tumors. The immune system does this by recognizing that the infecting organism or the tumor is foreign to the body and attacking it. One way the immune system attacks a foreign target is by making proteins called antibodies that bind to the target. Sometimes, for reasons we poorly understand, the immune system wrongly identifies part of our own body as being foreign and attacks it. This can result in disease such as some forms of diabetes and thyroid disease, as well as some neurological diseases. In this study, one tablespoon of blood will be removed from each subject and tested to see if the immune system is making antibodies against components of the nerves and muscles. We also hope to learn if these antibodies contribute to the development or worsening of illnesses of the nervous system. Only one blood draw is required, but subjects may be asked to give up to 8 additional blood samples to see if the level of antibodies changes over time. Any additional blood draws would be performed at regularly scheduled clinic visits. There would be at least 3 months between blood draws over a period of up to 3 years, if requested by the physician.

Depending on your diagnosis, the physician may also request the collection of mouth (buccal) cells. This takes about one minute and is painless. The cells are collected by swishing a swab around your mouth. This cheek swab would be done with each blood draw.

Please note that this study is conducted ONLY at UC Davis and that all participants must be seen in our clinic located in Sacramento, CA. Results of the testing performed in this study are not given to the participants. This study is not intended to treat or diagnose any condition.

Read the detailed description

The purposes of the study are to determine the frequency of auto-antibodies to 1) heat shock proteins and 2) to other molecules including cytoskeletal proteins such as rapsyn in diseases of the nervous system.

5cc of serum will be obtained from patients with multiple sclerosis and other autoimmune and inflammatory diseases of the nervous system including myasthenia gravis and transverse myelitis and from patients with other neurological diseases. Standard methodology to assure safe handling of serum will be used. Diluted serum will be tested for specific reactivity with heat shock proteins (Sigma Chemical Co., St. Louis, MO) as well as with other antigens in a standard ELISA as well as immunoblot.

Buccal swab will also be obtained in conjunction with each blood draw. Rapsyn and other cytoskeletal proteins will be extracted from Torpedo californica electric organ by means of differential centrifugation followed by alkali extraction. For the ELISA, a standard titration curve will be obtained for a positive control serum as previously determined. Negative control sera will be obtained from individuals with other degenerative neurological diseases. Titers of test serum will be determined as the dilution that generates a positive result that is two standard deviations from the mean of the background. Positive ELISA results will be confirmed by immunoblot. Patients may be tested at one time point only. If the serum is positive for specific antibody binding, additional serum samples may be obtained and retested up to 8 more times approximately 3 months apart. Correlation with severity of clinical findings and specific antibody titer will be made. Severity of clinical findings will be determined by the neurological exam done by the investigator.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood DrawOther

    A 5cc sample of serum will be drawn from each subject. Only one blood draw is required, but up to 8 additional blood draws can be obtained.

  • Cheek swabOther

    Also called Buccal swab

    A swab will be swished around the inside of the mouth to collect mouth (buccal) cells. This will be done with each blood draw.

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis and Myasthenia Gravis, run by University of California, Davis at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 18 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

If the serum is positive for specific antibody binding, additional serum samples may be obtained and retested up to 8 more times approximately 3 months apart. (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2026.
