An Acute Inflammation with Special Expression of CD11 & CD4 Produces Abscopal Effect by Intratumoral Injection Chemotherapy Drug with Hapten in Animal Model

Aim: To study the immunity reaction in tumor by intratumoral injection with a drug PYM and DNP, where it produces abscopal effect by the expression of immunological genes of tumor on home side (left side) while it brings a similar expression of same genes in tumor on opposite side (right side) of mice.

Method: Prepare each tumor on left side of 6 mice and injected intratumoral with a PYM+DNP and PYM control on day 1 and 7. Two day later of day 1, one of groups mice were inoculated with 0.2ml of H22 cells (105/ml) again on the right underarms as opposite side for controls. On day15, the tumor on bilateral sides were excised for qPCR measurement.

Result: It showed that inflammation with the expression of the CoL1a1, CD4, IL12aÂ, TGFb1Â, Elastin, Elastin, Cox2, CD11b/c, CD8, TNFa in different groups; The inflammation in both side of tumor but these is not only a increasing expression of Collal, CD4, IL12aÂ, TGFb1Â, Elastin, NFKB, Cox2, CD11c, CD8 and TNFa in tumor on home side of mice treated with PYM+DNP but also a similar an increasing expression of same genes in tumor on opposite side of mice which not treated at all. In the control group, it showed that inflammation without an expression of all factors related above immunity genes in both tumor on home treated with PYM only and opposite side of mice which not treated at all.

Conclusion: It indicated that PYM and hapten of DNP can induce an inflammation with stimulation of immunity reaction with the expression of the CoL1a1, CD4, IL12aÂ, TGFb1Â, Elastin, Elastin, Cox2, CD11b/c, CD8, TNFaÂ, which resulted in an abscopale effect. PYM can induce an inflammation but without expression of immuno genes, therefore, hapten is playing an important role with PYM in the special immunity reaction.

Serologic Response of SARS-CoV-2 mRNA-based Vaccines in Patients with Autoimmune Diseases

Background: In the spring of 2021, coronavirus disease 2019 (COVID-19) vaccines were approved and distributed in the United States for the public to combat the COVID-19 pandemic, but their rapid development leaves some questions unanswered. Vaccine efficacy has always been a point of interest for individuals with rheumatological diseases that take immunosuppressants. This study investigates the vaccine efficacy of two COVID-19 mRNA-based vaccines, Moderna and Pfizer, in subjects in West Texas patients with autoimmune diseases.

Materials and Methods: Blood was collected from Texas Tech University employees who received both doses of COVID-19 vaccines within the past nine months. Subjects were separated into either a group with a known history of rheumatic disease (n=18) or those without (n=18). The samples were analyzed for serum immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM) levels using specific enzyme-linked immunoassay kits, and a neutralizing antibody test using a surrogate virus was conducted as well. Results were analyzed using the Mann-Whitney U test (unpaired, two-tailed).

Results: There was no significant difference in serum IgG and IgA levels between the control and rheumatologic disease groups, but there were significant differences in serum IgM levels. All subjects cleared the threshold for the neutralizing antibody test.

Conclusion: The relatively similar serum IgG levels and the 100% detection rate of effective neutralizing antibodies across both groups indicate promising signs of serological response for subjects with autoimmune conditions, but the relatively low serum IgA and IgM levels of the study the group warrants further investigation.
