Abstract
Objective This study aimed to (1) collect and analyze statements about how to celebrate chiropractic in the present and roles that chiropractors may fulfill in the future, (2) identify if there was congruence among the themes between present and future statements, and (3) offer a model about the chiropractic profession that captures its complex relationships that encompass its interactions within microsystem, mesosystem, exosystem, and macrosystem levels. Methods For this qualitative analysis, we used pattern and grounded theory approaches. A purposive sample of thought leaders in the chiropractic profession were invited to answer the following 2 open-ended questions: (1) envision the chiropractor of the future, and (2) recommendations on how to celebrate chiropractic. Information was collected during April 2023 using Survey Monkey. The information was entered into a spreadsheet and analyzed for topic clusters, which resulted in matching concepts with social-ecological themes. The themes between the responses to the 2 questions were analyzed for congruence. We used the Standards for Reporting Qualitative Research to report our findings. Results Of the 54 experts invited, 32 (59%) participated. Authors represented 7 countries and have a median of 32 years of chiropractic experience, with a range of 5 to 51 years. Nineteen major topics in the future statements and 23 major topics in statements about celebrating chiropractic were combined in a model. The topics were presented using the 4 levels of the social-ecological framework. Individual (microsystem): chiropractors are competent, well-educated experts in spine and musculoskeletal care who apply evidence-based practices, which is a combination of the best available evidence, clinical expertise, and patient values. Interpersonal relationships (mesosystem): chiropractors serve the best interests of their patients, provide person-centered care, embrace diversity, equity, and inclusion, consider specific health needs and the health of the whole person. Community (exosystem): chiropractors provide care within integrated health care environments and in private practices, serve the best interests of the public through participation in their communities, participate through multidisciplinary collaboration with and within the health care system, and work together as a profession with a strong professional identity. Societal (macrosystem): chiropractors contribute to the greater good of society and participate on a global level in policy, leadership, and research. There was concordance between both the future envisioning statements and the present celebration recommendations, which suggest logical validity based on the congruence of these concepts. Conclusion A sample of independent views, including the perceptions from a broad range of chiropractic thought leaders from various backgrounds, philosophies, diversity characteristics, and world regions, were assembled to create a comprehensive model of the chiropractic profession. The resulting model shows an array of intrinsic values and provides the roles that chiropractors may provide to serve patients and the public. This study offers insights into the roles that future chiropractors may fulfill and how these are congruent with present-day values. These core concepts and this novel model may have utility during dialogs about identity, applications regarding chiropractic in policy, practice, education, and research, and building positive relationships and collaborations.

Abstract
Although the landscape for treating acute myeloid leukemia (AML) patients has changed substantially in recent years, the majority of patients will eventually relapse and succumb to their disease. Allogeneic stem cell transplantation provides the best anti-AML treatment strategy, but is only suitable in a minority of patients. In contrast to B-cell neoplasias, chimeric antigen receptor (CAR) T-cell therapy in AML has encountered challenges in target antigen heterogeneity, safety, and T-cell dysfunction. We established a Fab-based adapter CAR (AdCAR) T-cell platform with flexibility of targeting and control of AdCAR T-cell activation. Utilizing AML cell lines and a long-term culture assay for primary AML cells, we were able to demonstrate AML-specific cytotoxicity using anti-CD33, anti-CD123, and anti-CLL1 adapter molecules in vitro and in vivo. Notably, we show for the first time the feasibility of sequential application of adapter molecules of different specificity in primary AML co-cultures. Importantly, using the AML platform, we were able to demonstrate that chronic T-cell stimulation and exhaustion can be counteracted through introduction of treatment-free intervals. As T-cell exhaustion and target antigen heterogeneity are well-known causes of resistance, the AdCAR platform might offer effective strategies to ameliorate these limitations.

Abstract
We have previously reported that Insulin-like growth factor (IGF-I) is a cellular growth factor of human transformed T-lymphocytes. To evaluate the role of IGF-I for nontransformed T-cells we investigated synthesis of IGF-I and the influence of an IGF-I antiserum, UBK487, during proliferation process. IGF-I is synthesized by B-lymphocytes and monocytes during proliferation. Via the T-cell receptor (CD3 subunit) induced proliferation of resting T-cells was inhibited by addition of UBK487. The addition of monocytes to the resting T-cell fraction reversed the UBK487 effect. Using UBK487, a 12 kDa protein could be immunoprecipitated from unstimulated or PHA stimulated T-cells whereas a 36 kDa protein could be immunoprecipitated from OKT3 stimulated T-cells.
