“…The hemoglobin instability can be explained as a consequence of an abnormal connection between the alpha and beta globins, especially in the α1β1 contacts, and also the blockage of the side chain (SH radical) of the amino acid cysteine (Cis) that occupies position 93 of the β polypeptide chain ( 76 , 78 ). Decreases in the globin attraction to its heme groups are consequences of amino acid replacements that participate in the molecule stabilization and of changes in those aminoacidic residues spatially surrounding the heme group ( 79 , 80 ). If these processes occur in the β globin, reactive changes of side chains would be expected.…”

“…Hemorphins have several activities, such as: antinociception acting as opioid receptor agonists ( 91 , 94 , 95 ); modulation on the activity of the calmodulin-dependent enzyme ( 96 ); inhibition of encephalin degradation ( 97 ) and angiotensin-converting-enzyme ( 78 ); induction release central β-endorphins ( 82 ), and; oxytocinergic activation ( 79 ). Hemoglobin-derived peptides also display antinociceptive ( 91 ) and cardiovascular effects ( 98 , 99 ), increases spatial learning ( 100 , 101 ) and cholinergic neurotransmission ( 102 ), modulates the pituitary-adrenal axis and reduces the activity of calcineurin ( 103 ).…”

Introduction : The evolving COVID-19 pandemic became a hallmark in human history, not only by changing lifestyles, but also by enriching scientific knowledge on viral infection and its consequences. Objective : Although management of cardiorespiratory changes is pivotal to a favorable prognosis during severe clinical findings, dysregulation of other systems caused by SARS-CoV-2 infection may imbalance erythrocyte dynamics, such as a bidirectional positive feedback loop pathophysiology. Method and Results : Recent evidence shows that SARS-CoV-2 is capable of affecting the genetics and dynamics of erythrocytes and this coexists with a non-homeostatic function of cardiovascular, respiratory and renal systems during COVID-19. In hypothesis, SARS-CoV-2-induced systematical alterations of erythrocytes dynamics would constitute a setpoint for COVID-19-related multiple organ failure syndrome and death. Conclusion : The present review covers the most frequent erythrocyte-related non-homeostatic findings during COVID-19 capable of providing mechanistic clues of SARS-CoV-2-induced infection and inspiring therapeutic-oriented scientific evidence.

“…Through different mechanisms, LVV-H6 and LVV-H7 reduced anxiety-like responses in the elevated plus maze paradigm and depression-like behavior as assessed by immobility time during forced swim tests. 62 , 63 The effects of LVV-H7, in particular, were dependent on oxytocin receptors, since agonistic actions upon the AT4 receptor are postulated as a path to reducing oxytocin degradation exerted by this IRAP catalytic domain in physiological conditions. 15 , 39 , 64 Consequently, the antagonism of oxytocin receptors blocked the central effects of peripherally injected LVV-H7 in naive rats.…”

Follow-up of patients affected by COVID-19 has unveiled remarkable findings. Among the several sequelae caused by SARS-CoV-2 viral infection, it is particularly noteworthy that patients are prone to developing depression, anxiety, cognitive disorders, and dementia as part of the post-COVID-19 syndrome. The multisystem aspects of this disease suggest that multiple mechanisms may converge towards post-infection clinical manifestations. The literature provides mechanistic hypotheses related to changes in classical neurotransmission evoked by SARS-CoV-2 infection; nonetheless, the interaction of peripherally originated classical and non-canonic peptidergic systems may play a putative role in this neuropathology. A wealth of robust findings shows that hemoglobin-derived peptides are able to control cognition, memory, anxiety, and depression through different mechanisms. Early erythrocytic death is found during COVID-19, which would cause excess production of hemoglobin-derived peptides. Following from this premise, the present review sheds light on a possible involvement of hemoglobin-derived molecules in the COVID-19 pathophysiology by fostering neuroscientific evidence that supports the contribution of this non-canonic peptidergic pathway. This rationale may broaden knowledge beyond the currently available data, motivating further studies in the field and paving ways for novel laboratory tests and clinical approaches.
