The intensity of delayed-type hypersensitivity (DTH) expression measured by footpad swelling was established in high and low antibody responder lines of mice produced by bidirectional selective breeding for antibody responsiveness to different antigens. These lines of mice presented a very large difference in antibody response to the antigens used in each selective breeding (selection Ags) and to several other unrelated Ags (nonspecific effect). The intensity of DTH reactivity to selection Ags and to unrelated Ags differed in the various lines investigated, but the intensity of DTH reactions was not correlated with antibody responsiveness. The results of the present article demonstrated that the expression of DTH reactivity and antibody responsiveness to the same antigens are polygenic characters subject to independent quantitative regulation.

Safety and immunogenicity of an mRNA-1273 vaccine booster in adolescents.
Hum Vaccin Immunother
December 2025
Research and Development, Infectious Disease, Moderna, Inc., Cambridge, MA, USA.
Safety, immunogenicity, and effectiveness of an mRNA-1273 50-μg booster were evaluated in adolescents (12-17 years), with and without pre-booster SARS-CoV-2 infection. Participants who had received the 2-dose mRNA-1273 100-µg primary series in the TeenCOVE trial (NCT04649151) were offered the mRNA-1273 50-μg booster. Primary objectives included safety and inference of effectiveness by establishing noninferiority of neutralizing antibody (nAb) responses after the booster compared with the nAb post-primary series of mRNA-1273 among young adults in COVE (NCT04470427).

Purpose: Mesothelin (MSLN) is highly expressed in high grade serous/ endometrioid ovarian cancers (HGOC). Anetumab ravtansine (AR) is an antibody drug conjugate directed at MSLN antigen with a tubulin polymerization inhibitor. We assessed safety, activity and pharmacokinetics of the combination AR/bevacizumab (Bev) (ARB) versus weekly paclitaxel (wP)/Bev (PB) in patients with platinum resistant/refractory HGOC (prrHGOC).

Schepens Eye Research Institute, Massachusetts Eye and Ear Infirmary, Department of Ophthalmology, Harvard Medical School, Boston, Massachusetts, United States.
Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.
Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.
The efficacy and safety of suvemcitug, envafolimab, and FOLFIRI in microsatellite-stable or mismatch repair-proficient colorectal cancer: preliminary results of a phase 2 study.
Int J Colorectal Dis

Internal Medicine, Jilin Cancer Hospital, Changchun, China.
Purpose: This phase II study is designed to evaluate the combination therapy involving suvemcitug and envafolimab with FOLFIRI in microsatellite-stable or mismatch repair-proficient (MSS/pMMR) colorectal cancer (CRC) in the second-line treatment setting.
Methods: This study is a non-randomized, open-label prospective study comprising multiple cohorts (NCT05148195). Here, we only report the data from the CRC cohort.
Novel Sarcoidosis Epitope Augments MHCII, CD80/CD86 Expression, Promotes B-Cell Differentiation and IgG Production.

Numerous chronic human disorders are associated with immune activation by obscure antigen(s). We identified a novel sarcoidosis-epitope (ChainA) by immunoscreening of a novel T7 phage library and confirmed an abundance of ChainA IgG-antibody in sarcoidosis. We tested whether ChainA epitope elicits immune responses through B-cell activation, plasma cell differentiation and antibody production.
