γδ T cell characterisation in the long term after haematopoietic stem cell transplantation and its impact on CMV control and cGVHD severity
Alagrafi F, Stikvoort A, Gaballa A, Solders M, Ringden O, Poiret T, et al.
Clin Transl Immunology . 2025 Mar; 14(3):e70027. PMID: 40059884
Objectives: The clinical outcome after allogeneic haematopoietic stem cell transplantation (aHCT) relies greatly on the efficient recovery of T cells. Several studies have investigated the short-term γδ T cell reconstitution...

The Novel HLA-DQA1*05:90 Allele Detected in a Bone Marrow Donor Candidate Using Next-Generation Sequencing
Gaballa A, Soderstrom A, Lundin N, Eich T
HLA . 2025 Feb; 105(2):e70063. PMID: 39957014
A single nucleotide mismatch within exon 4 of HLA-DQA1 differentiates the novel DQA1*05:90 allele from DQA1*05:09:01:03.

The extracytoplasmic sigma factor σ supports biofilm formation and increases biocontrol efficacy in Bacillus velezensis 118
Cai Y, Tao H, Gaballa A, Pi H, Helmann J
Sci Rep . 2025 Feb; 15(1):5315. PMID: 39939707
Plant growth promoting rhizobacteria (PGPR) offer an environmentally friendly and sustainable approach to combat pathogens and enhance crop production. The biocontrol activity of PGPR depends on their ability to colonize...

Site-selective modifications by lipid A phosphoethanolamine transferases linked to colistin resistance and bacterial fitness
Schumann A, Gaballa A, Yang H, Yu D, Ernst R, Wiedmann M
mSphere . 2024 Nov; 9(12):e0073124. PMID: 39611852
Importance: Rising levels of resistance to increasing numbers of antimicrobials have led to the revival of last resort antibiotic colistin. Unfortunately, resistance to colistin is also spreading in the form...

Deciphering the Molecular Mechanism of Peracetic Acid Response in Listeria monocytogenes
Arvaniti M, Gaballa A, Orsi R, Skandamis P, Wiedmann M
J Food Prot . 2024 Nov; 88(1):100401. PMID: 39515609
Peracetic acid (PAA), a strong oxidizing agent, has been widely used as a disinfectant in food processing settings as it does not produce harmful chlorinated by-products. In the present study,...

Next-Generation Sequencing Reveals the Novel HLA-DQA1*06:01:04 Allele in a Bone Marrow Donor
Gaballa A, Soderstrom A, Lundin N, Eich T
HLA . 2024 Oct; 104(4):e15729. PMID: 39462172
A single nucleotide mismatch within exon 2 of HLA-DQA1 differentiates the novel DQA1*06:01:04 allele from DQA1*06:01:01:01.

The multifaceted roles of phosphoethanolamine-modified lipopolysaccharides: from stress response and virulence to cationic antimicrobial resistance
Schumann A, Gaballa A, Wiedmann M
Microbiol Mol Biol Rev . 2024 Oct; 88(4):e0019323. PMID: 39382292
SUMMARYLipopolysaccharides (LPS) are an integral part of the outer membrane of Gram-negative bacteria and play essential structural and functional roles in maintaining membrane integrity as well as in stress response...

Selective lysis of acute myeloid leukemia cells by CD34/CD3 bispecific antibody through the activation of γδ T-cells
Al Agrafi F, Gaballa A, Hahn P, Arruda L, Jaramillo A, Witsen M, et al.
Oncoimmunology . 2024 Jul; 13(1):2379063. PMID: 39076247
Despite the considerable progress in acute myeloid leukemia (AML) treatment, relapse after allogeneic hematopoietic stem cell transplantation (HSCT) is still frequent and associated with a poor prognosis. Relapse has been...
